How long does deal analysis actually take you?

Question

I am beginning my real estate Investment and I just spent 3-4 hours analyzing a property in Excel, and even then, I am not sure about my calculation. Is this normal, or am I overthinking and overanalyzing?

For those who done this for a while:How long does it typically take you to fully analyze a deal?What tools are you utilizing? (BP Calculator, Excel, Something else?)What metrics do you use to determine if it is a good deal or not?

Also, have you ever missed out on any opportunities because your analysis took too long to finish? Are there any tools that could perform this analysis and give you a verdict (Good, Maybe, Bad deal), and how much would the tool cost?

Thank you

Early on, spending a few hours per deal is common. With repetition, that usually drops to minutes for a first-pass analysis and more time only on deals that survive the initial screen.The key shift is separating “quick filter” analysis from deeper underwriting.

I have a comprehensive sheet that I spent 10 hours to build. After that, everything is pretty straightforward and automatically generated with 2-3 inputs, and each property takes about 5 minutes.

If you come across any deals you’re considering, buy & hold, flip, whatever. I’d be happy to take a look and give you a clear idea of what I think the deal is actually worth and any red flags I see. I specialize in real estate underwriting and would be happy to take a deeper look at any properties you have.

Completely normal starting out... honestly I’d rather see someone spend a few hours understanding a deal than rush into something they don’t fully get.

What I’ve seen over time is it really breaks into two speeds:

– Quick filter (5–10 min): Does this even have a chance to work?
– Deep dive: Only if it passes that first screen

The biggest shift isn’t the tool (Excel vs calculators), it’s getting better at your assumptions, rents, expenses, and exit. That’s what actually drives the deal.

Early on it takes longer because you’re building that muscle. Eventually you’ll be able to tell pretty quickly what’s worth your time and what isn’t.

If anything, the bigger risk isn’t taking too long — it’s getting comfortable with bad assumptions.

3–4 hours is pretty normal starting out, especially in Excel. Thats also kind of the problem with excel. you can spend hours building something and still not feel confident in the answer or just waste a lot of time fixing equations.

At this point I try to get to a “yes / no / maybe” as fast as possible. Most deals don’t need perfect precision, they just need to be directionally right. If I can’t tell within a few minutes whether something is even close to working, I usually move on. If it passes that quick filter, I’ll spend more time dialing it in and stress testing it.

Tools definitely help with this. Being able to plug in numbers quickly and test different scenarios side by side makes a big difference.

An experienced investor can do "napkin math" in a couple of minutes and make a decision shortly after

Experienced investors know what works and what doesn't. 3-4 hours on a property is likely overthinking it, but can make sense if you're very new just trying to understand and study how it works.

Griwan, 3-4 hours on your first few deals is completely normal — you're not overthinking it. You're learning what matters, and that takes time upfront. The speed comes with reps.

Here's what to expect as you keep going:

Your first 10 deals will take 2-4 hours each because you're building your spreadsheet, second-guessing formulas, and figuring out which assumptions actually move the needle. After 10-20 deals, you'll be down to 45-90 minutes because your template is dialed in and you stop modeling things that don't matter. After 50+ deals, you'll do a 15-minute quick screen and only go deep on the ones worth it.

On your Excel concern — the fact that you're not sure about your calculations is actually a good sign. It means you're thinking critically instead of just trusting a formula you copied from YouTube. One thing that helped me early on was back-testing my model against a deal with known numbers (like a listing that shows actual income/expenses). If your model spits out roughly the same NOI and cash flow as the listing shows, your formulas are probably fine.

For the metrics question, here's what I'd focus on at your stage:

Cash-on-cash return — this is your real return on the cash you actually put in. I use this as my primary filter. Below 8% and I need a really good reason to keep looking at it.

DSCR — can the property pay its debt from income alone? Lenders want 1.2x minimum, I want 1.3x+ so there's a cushion for vacancies or surprise repairs.

Cap rate — useful for comparing similar properties in the same market, but don't compare a Philly cap rate to a Kansas City cap rate. They're different markets with different risk profiles.

Expense ratio — if operating expenses are eating more than 45-50% of gross income, figure out why before you go further.

To answer your question about missing deals because analysis was too slow — yes, early on. But the fix wasn't finding a faster tool. It was learning to screen faster. Before I open any spreadsheet now, I spend 5 minutes looking at price, realistic rent potential, and property condition. That alone filters out 80% of listings and saves hours.

Keep grinding through the deals. 20 more from now and you'll be twice as fast without even realizing it.

yep.

2 questions for me.

1. do I want to own in this area?  2. could I get most or all of my capital back on a BRRRR?

that's it.

Steve K. · Answer

The main things that I look at are location and comps. Since I know my market very well, I know whether a location is good or not immediately, and usually know most of the comps already too but usually run them quickly anyway, it takes a few minutes. I just need to know if I’m buying in a good location and what price I need to pay to capture instant equity. I don’t bother with spreadsheets or analysis tools at all anymore. The three golden rules of real estate are location, location, and location. If you don’t know your market well enough to distinguish between a good location or not, and a good price or not, your best bet will be to work closely with a professional and learn your market until you do. Spreadsheets are a waste of time and often mislead people into bad locations because worse locations often have better spreadsheet results but worse actual results in reality when it comes to operating the property due to things you can’t predict like higher turnover, tenant defaults, property damage and theft, lack of rent and price appreciation compared to good locations, etc. Most people underwrite properties like good locations and bad locations will perform the same when they definitely don’t.
