I don’t make offers based on gut feelings. I used to — early on, I got burned a few times. Now I have a system: a clear property evaluation process I run through before I commit a single dollar to any deal. If you’re serious about real estate investing, you need a repeatable process too. Here’s mine.
Why a System Beats Intuition Every Time
Emotions make bad real estate decisions. You fall in love with a property, you ignore the red flags, you overpay. Or the opposite — you pass on a deal because it looks rough, but if you’d run the numbers, you’d have seen significant upside. A systematic evaluation removes the emotion and replaces it with data. Every time, same steps, same questions, same discipline.
Step 1: Verify the Numbers Before You Set Foot in the Door
Before I ever schedule a walkthrough, I pull the following:
Comparable sales (comps). What have similar properties sold for in the last 90 days within a half-mile radius? I want recent, relevant data — not what someone sold two years ago in a different market cycle. This gives me my ARV: the after-repair value.
Property tax records. Who owns it, how long have they owned it, and what have they paid in taxes? This tells me whether I might be dealing with a motivated seller or someone who’s been sitting on equity for decades and has unrealistic expectations.
Ownership history. Multiple transfers in a short period can signal problems. Long-term ownership with no work done often signals deferred maintenance — which means scope creep on rehab costs.
Liens and title issues. I check for outstanding mortgages, mechanic’s liens, tax liens, and HOA dues. A property can look like a great deal on the surface and have $40,000 in back debt attached to it.
Step 2: The Walkthrough — What I’m Actually Looking For
Once the numbers pass the first filter, I walk the property. I’m not looking at the paint color or the light fixtures. I’m looking at the big-ticket items that determine whether a deal pencils out.
Foundation and Structural
This is the non-negotiable. Cracks in the foundation, bowing walls, floors that sag or bounce, doors that don’t close properly — these are structural red flags. Foundation work in Illinois can run $10,000 to $50,000 or more. If I see structural issues, the deal needs to account for that cost or I walk.
Roof
I ask the age of the roof upfront and verify it visually. Missing shingles, granule loss, soft spots around chimneys and flashing — all of these indicate remaining life. A new roof on a typical Chicago suburb single-family runs $8,000 to $15,000. I either price that in or negotiate it out of the purchase price.
Mechanicals — HVAC, Plumbing, Electrical
I check the age and condition of the furnace and water heater. I look at the electrical panel — is it 100 amp or 200 amp? Does it have Federal Pacific or Zinsco breakers (major liability)? I check under sinks for water damage and signs of active or old leaks. Cast iron drain lines in older homes can add $5,000 to $15,000 in plumbing work. I price everything.
Layout and Marketability
Even after rehab, will this property appeal to buyers or renters in this market? Bedroom count, bathroom count, layout flow, natural light — these matter. A 3-bed/1-bath in a neighborhood of 3-bed/2-bath homes is going to struggle at resale. Can I add a bathroom within budget? If not, does the reduced ARV still work?
Step 3: Build the Scope and Estimate Costs
After the walkthrough, I build a line-item scope of work. Every category: demo, framing, rough plumbing, rough electrical, HVAC, insulation, drywall, flooring, tile, fixtures, cabinets, countertops, interior doors, exterior, landscaping, permits. I don’t use round numbers — I get specific. Specificity protects your budget.
I then add a 10-15% contingency on top of the estimate. Something always comes up. A wall you open that has mold. A subfloor that needs replacing. Budgeting for the unknown prevents it from killing your deal when it happens.
Step 4: Calculate the Maximum Allowable Offer
Here’s the formula I use: MAO = ARV × 70% − Repair Costs. This 70% rule accounts for holding costs, transaction costs, financing costs, and profit. If you’re using hard money, or if the market is slower, you may need to use 65%. If you’re paying cash and moving fast, sometimes 75% works. But the math has to work — not your optimism.
If my maximum allowable offer is below what the seller wants, I either negotiate or walk. Simple as that. No deal is better than a bad deal.
Step 5: Know Your Exit Before You Make Your Offer
Do I flip it or hold it? Before I make an offer, I need to know my exit strategy. If I flip it, I’m targeting a specific buyer pool in that market. If I hold it as a rental, I need to know the rent-to-value ratio and whether the cash flow makes sense. Sometimes a property that doesn’t work as a flip makes a great rental, or vice versa. Clarity on exit determines how aggressively I pursue the deal.
For deals I’m buying to flip, Redeveloped Properties handles the acquisition and renovation. For finding the right contractors to execute the rehab, I use Fix N List to source and vet tradespeople.
Frequently Asked Questions: Property Evaluation Before Making an Offer
How long does a proper property evaluation take?
My desk research takes 30 to 60 minutes. The walkthrough takes 1 to 2 hours depending on the size and condition. Then another hour to build the scope and run the numbers. Total: half a day if I’m moving fast. Don’t rush this process — the money is made or lost here.
Should I get a home inspection before making an offer?
For motivated seller / distressed property deals, usually not before the offer — the timeline doesn’t allow it. I rely on my own walkthrough and price in contingency. I do use an inspection contingency in my contract when possible, which lets me renegotiate or exit if the inspection reveals something major I missed.
What’s the biggest mistake first-time investors make when evaluating a deal?
Underestimating repair costs. Every first-timer does it. The solution is to bring a contractor on the walkthrough before you make your offer. Their estimate will be more accurate than yours, and it protects you from buying a problem you can’t afford to fix.
How do you handle multiple offers on the same property?
I don’t chase. I run my numbers, I make my offer at my number, and I move on if I lose. There are always more deals. The investors who get in trouble are the ones who start bidding emotionally to “win” a deal. Winning at the wrong price isn’t winning.
This property evaluation process is the foundation of every deal I do. Get this right, and everything downstream gets easier. Get it wrong, and no amount of hustle will save you. Reach out if you want to talk through your next deal — I’m always happy to look at numbers with someone who’s serious.
