Underwrite every lead
not just the promising ones
Your maximum offer rests on two numbers you usually have to guess. Propera produces both from verified comps and applies your own formula, so every seller conversation starts with a real number.
Wholesaling breaks at the point where marketing outruns underwriting. Leads arrive faster than anyone can comp them, so the ones that look unpromising get a rough number or none at all, and rough numbers fall apart later at the buyer's inspection. Propera produces the after repair value from condition-graded comps whose sale prices are verified against a second public source, builds an itemized repair budget from a plain-language description of the property, and applies the offer formula you configured. The same method runs on every lead, including the ones you would not have had time to look at.
Where wholesale deals actually go wrong
Leads arrive faster than you can comp them
Marketing produces more leads than manual comping gets through. The rest get a rough offer or no offer, and a rough offer either loses the deal or gets renegotiated after the buyer runs their own numbers.
Your MAO is only as good as two inputs
The arithmetic in the 70% rule is trivial. The two numbers you feed it are not. An ARV needs comps that sold in the condition the house will resell in, and a per-square-foot repair figure describes the average house rather than this one. Offer too little and you lose the contract; offer too much and the margin is gone before you assign it.
Your buyers re-run your numbers
Serious cash buyers comp every deal themselves. If your ARV does not survive that, you lose the assignment first and the buyer relationship shortly after.
What changes
Your formula, applied identically every time
You set the minimum and maximum ARV percentages, your assignment fee, an offer floor and ceiling, and a rehab multiplier. Every lead runs through the same math, so two deals underwritten a month apart are actually comparable.
A repair number you can walk a buyer through
Describe the condition in plain language and get a line-item budget back, priced against cost settings you control. When a buyer questions the number you can show them which lines produced it rather than defending a lump sum.
Comps that survive the buyer checking them
Every comp is graded for the condition it sold in and for whether the sale was a genuine retail transaction, and each recorded sale price is verified against a second public source. Comps that fail verification are excluded rather than quietly averaged in.
New leads underwritten as they arrive
On the Pro and Business plans, Propera underwrites inbound CRM leads automatically and writes the ARV, the comps and the Zillow links back onto the record. Connect through Zapier, Make, Podio GlobiFlow, GoHighLevel, or any webhook.
One deal, and whose number to trust
Luke had offered $90,000 without much confidence in it. A more experienced investor put the maximum at $110,000, which lands inside Propera's range while Luke's own number sits below the floor. The useful outcome was not being told he was right. It was knowing which of the two numbers to trust, and that he had been bidding under his own ceiling.
From a recorded session with Luke, Wholesaler. One property, so read it as an illustration rather than as evidence of accuracy.
“Takes me 30 minutes to pull comps and [Propera] would allow me to get them instantly.”
Every comp carries its grade
A renovated sale and a distressed sale on the same street support very different numbers. Propera grades each comp on the condition it sold in and on whether the sale was a genuine retail transaction, adjusts its price per square foot toward renovated-equivalent based on that grade, then weights it by how confident the grade is. A dated sale still counts, at what it is worth.
Questions people ask
Does Propera calculate my maximum allowable offer?
Yes, using your numbers rather than a built-in rule. You set the ARV percentages that define your offer range, a flat assignment fee, an offer floor and ceiling, and a rehab multiplier. Propera produces the ARV and the repair estimate, then applies that formula. If you work on a different basis than the 70% rule, you configure it that way once and every deal follows it.
Do I still need my lead generation software?
Yes. Propera does not build lists, skip trace, or send mail. It underwrites the leads your existing stack produces. On Pro and Business it connects to that stack directly, so new leads are underwritten as they land and the results are written back onto the record.
How is this different from a wholesaling calculator?
A calculator asks you for the ARV and the rehab budget and does the arithmetic. Those two figures are the hard part and the expensive part to get wrong. Propera produces them from data, then does the arithmetic with your formula.
Can I use it in markets I do not know?
Yes, on any address in the United States, without MLS membership. Comp quality follows sales density, so a virtual deal in a dense suburb behaves like a local one, while rural properties with sparse comparable sales carry a lower confidence score and should be treated accordingly.
What happens when a property has almost no comps?
Propera widens the search rather than inventing a number, and the confidence score reflects how hard the comps were to find. A low confidence result is a signal to verify before you commit, not a number to put in front of a seller.
Run a property you already know
The fastest way to judge the comps is on a deal you underwrote yourself.
