How should I prioritize an off-market property list before calling or mailing every owner?

Start from a list you've already narrowed by combining property filters. The order here suits an investor who buys houses to renovate and resell, and whose scarce resource is calling time. The checks that can remove a record run before anything is bought, so a record that fails early never costs a phone number.

The buy box leads because the answer is already on the list grid. Property type, city or ZIP code and Estimated Value are all there, so a duplex on a single-family buyer's list comes off the campaign whatever else the record shows.

Ownership comes second, and it can take real work on a record with a recent deed. The Transactions tab in PropertyRadar's property profile has a Current Owner view, and the county's current ownership record is where to check a doubt. If the property has changed hands, replace the owner and start that record over, or remove it. It runs early anyway, because the later checks look at one owner's loans, events and phone numbers.

The economics come third, and they need two estimates from you: an after-repair value and a repair cost. BiggerPockets states the 70% rule as paying no more than 70 percent of the after-repair value, minus repairs. Its example is a $150,000 house needing $20,000 of work. Seventy percent of $150,000 is $105,000, and subtracting the repairs leaves a maximum of $85,000. The same article calls the rule a guideline and says the percentage runs as high as 80 or 85 in California, so set your own.

Compare that maximum with the loans on the property. PropertyRadar's Estimated Value minus its Estimated Equity gives a modeled figure for open loans. It isn't a verified payoff, and other liens, back taxes and closing costs all move the real number. So this check only routes records. A house with $40,000 in modeled loans against an $85,000 maximum goes forward. One with $130,000 in modeled loans gets its payoff and liens looked into before anyone spends calling time on it.

A record that clears the economics is worth looking up for a dated public event. The Foreclosures section of the Transactions tab shows recorded foreclosure notices. Tax delinquency shows in the tax delinquency fields and on the county's own list. No record fails this check, because its job is to decide whether the owner gets a call or a letter first.

Contact comes last because it's where the spending starts. Mail Vacant flags a mailing address the Postal Service has identified as vacant, and a clear flag doesn't confirm that mail will be delivered. For phones you already hold, PropertyRadar's owner profile marks an Active number with a green checkmark and uses a yellow triangle for Opted Out, Wrong Person, Disconnected or Do Not Call. The Do Not Call status appears only if your account has accessed DNC data. A green icon alone isn't a registry result, so every number you plan to dial still goes through your do-not-call and suppression screen.

A number that clears the screen points to a person, and it doesn't confirm that the person holds title or can sign. Use the first call to confirm you've reached the owner of record, along with the other checks before contacting an owner. When the owner is an LLC or a trust, find the decision-maker first. An owner whose only number is already marked Wrong Person gets mail now and moves to the steps for an owner with no valid phone.

Owners with a dated event are group 1. Mail them and buy their phone numbers, then call once the numbers have passed the do-not-call screen. In PropertyRadar, set their status to Contact Owner and their Interest Level to five stars, so the whole group can be selected again later.

Owners without an event and with a high score get a letter before a call, since a letter takes none of your dialing hours. The modeled score decides what happens after that. A High or Very High score, which is 61 to 100 on PropertyRadar's bands, puts an owner in group 2. You buy those phone numbers only if calling time is left after group 1, and three stars marks the group. Owners with a Medium or lower score, or no score, form group 3. They stay on the list with one star until the scores update, which happens monthly in PropertyRadar, and then you look again.

Some records can't be placed yet. A house flagged at the economics check goes to research, and so does an owner with no reachable address or number. Give each one a status of Check Value or Research Title and a note saying what's missing. These records cost nothing in contact spend until that question is answered.

PropertyRadar lets you tag in bulk, which keeps the sorting quick. A status label or an Interest Level can be set on up to 1,000 selected records at once. To order group 2, add the Likely Listing column from the column chooser and sort on it. A blank cell means the property has no score, and a filter with only a Max value leaves unscored properties out, so count the blanks before you filter. An owner with a dated event and a blank score still belongs in group 1.

A county record carries a date anyone can look up. That gives the caller a reason for contact that holds up when the owner asks where it came from. Mecklenburg County's delinquent taxpayer lists show what one looks like. The Top 100 list says it reflects the tax record as of October 2, 2026. The advertisement notice names the real property owner on the tax records as of the January 6, 2026 delinquent date.

That second date carries a caution of its own. A notice built on a January 6 owner name doesn't say who holds title today, which is the reason the owner check runs before the event check.

PropertyRadar's Likely to List for Sale score ranks a property's relative likelihood of being listed in roughly the next six months, on a scale of 0 to 100. PropertyRadar describes it as directional and meant for relative prioritization. The score has an as-of date, but it doesn't point to a particular record you could name to the owner. A listing is also a different outcome from an off-market sale. So the score sets the order inside group 2, and it doesn't promote a record into group 1. How to use likely to sell scores covers reading the bands.

Suppose an investor who buys single-family homes in one county applies the 70 percent formula to five records from an absentee-owner list.

Record D would top a call list sorted by events alone. Here it goes to research, and it returns to group 1 if the confirmed payoff and liens fit under the maximum offer. Record E waits on a deed. If that deed turns out to be a full conveyance, the event belongs to a person who no longer holds title, so the former owner comes out of the mailing and the new owner starts the checks from the beginning.

Your calendar sets the size of the weekly batch. Owners per week equals calling hours times dials per hour, divided by the attempts you give each owner.

Suppose one person dials for 6 hours a week, makes 15 dials an hour and gives each owner 3 attempts. That's 90 dials, or 30 new owners a week and about 130 a month. If group 1 holds 140 owners, it takes just under five weeks to work. Group 2 gets mail during that time, with no phone purchase.

Buy phone numbers one weekly batch at a time. PropertyRadar's pricing page includes 250 phones and emails a month on Solo and charges 8 cents for each additional contact. Unused allowance doesn't carry into the next month. If each owner is one billable phone contact, 30 owners a week is about 130 contacts a month, which fits inside the 250. The Purchase Summary shows what the selected records will cost before you buy, so read it for each batch.

A much larger group 1 changes the plan. With 600 owners, the same caller needs 20 weeks, and an event dated the week you pulled the list is five months old by the last call. In that case, call the most recently dated events first and start the older ones in mail. Give every waiting record a recheck date, and confirm the event and the owner with the county again before the call.

Record each outcome on the property the day it happens. PropertyRadar's list filters for the most recent call, text, voicemail, direct mail and email reflect only campaigns sent through PropertyRadar and its WAVV dialer. A call made from your own phone needs a note and a status change to show up later. Likely Transactions values aren't included in file exports either, so do the ranking and tagging inside PropertyRadar and export the tagged group.

Each month, log a few numbers for each group: owners mailed, owners called, mail responses, conversations with a confirmed owner, appointments or offers, and what the mail and contact data cost. Note how many owners each check removed as well. That count shows which check is doing the work and which list filter to tighten upstream.

Compare groups only where the treatment matches. Mail response per 100 owners mailed can be compared across groups for the same drops. Conversations per 100 owners called applies only to owners who were called with the same number of attempts. To find out whether a high score deserves calls, call a sample of group 2 on the same schedule as group 1 and compare the two rates.
