How to Analyze Deals - Finding Rent Amounts

Question

Aaron Zimmerman · Answer

rentometer is a great resource for trying to find rents.

I'd also look at active listings to see what rents are in the area for a comparable unit (SF and finishes)

Welcome to BP—and congrats on getting started early. House hacking a duplex is a great first move.

There are a few solid ways to dial in market rent, and I like to cross-check multiple sources rather than rely on just one:

• Rentometer – Great for quick validation. Plug in the address and bedroom count to get a rent range and see how it compares to nearby comps.
• HotPads – Filter by property type, bed/bath count, and zip code to see active listings. This gives you a real-time view of what landlords are currently asking.
• Zillow & Facebook Marketplace – These are especially useful for judging demand. On Zillow, pay attention to how long a listing has been active and how many contacts it’s received—both are strong indicators of whether the rent is realistic. Saving listings and watching how long they sit can also tell you a lot about vacancy and pricing pressure.

Beyond online tools, don’t underestimate local insight. Reaching out to property managers and investor-friendly Realtors in the area can give you a clearer picture of average rents, vacancy rates, and tenant demand by neighborhood. That local context is incredibly valuable—especially when underwriting a house hack.

The goal isn’t just “what can I charge,” but “what will rent quickly and consistently.”

Hi there,

Welcome to BP!!! A great place to start.

It depends where are you looking for, rentometer and zillow are sort of accurate in areas with enough similar comparables, if that is not your case, you have to rely more on look property by property to see if those are similar than yours.

As agents we have access to history so that sometimes helps, if you have one, I would say to rely on his/her data.

Investing is a very analytic job so I always recommend to run your number even when you have someone that is helping you.

HUD has their fair market rents in every state and town. It will give you current and projected. I think its great when evaluating a deal.

Rentometer is great for a quick analysis.For a more accurate ones you would need to run comps in Zillow, adjust prices for each comp condition. Or you can use RentJudge, it does that for you for free.

Richard Loniewski · Answer

Simple, just look at rents in the area through Zillow or a few other rental sights like Apartments.com, just make sure the rentals are similar and close in distance.

Andrea O. · Answer

Rentometer is a good starting point. For a more accurate estimate, you need to adjust comparable property prices based on condition and amenities. You can do this manually, or save time by using an automated tool (check my profile).

If you want to DIY and have the time, look up rentals in the area and see what others are charging.

Know your neighborhood.  Drive it frequently.  Call on the rental signs and ask what the rent is.  That should be doable in many areas as the duplexes seemed to be grouped together.

See how those match up with your budgets.

If you want to leverage your time, gGet a great realtor on your team who knows rents and can provide accurate closed rent prices, vs just the landlord wish prices.  Many of those are not accurate today.

One thing I will say is....for the most part duplexes are pretty tough house hacks in many cases today.  Most of what I see will have you paying your full share of the rent and probably subsidizing the rent for your tenant.  This is due to runup in housing prices the past 5-6 years, but low rent growth.   You best hacks today are probably to buy 4-5-6 bedroom house and rent by the room.   Of course either way you have to have your wife on board with your plan.  It may not be your situation, but I see it kill probably 80% of house hack plans.  Men and women think differently.  Often men don't mind small and ugly homes if they think they can build some wealth. Women often think of clean, nice, shiney, good neighborhood to raise kids and good schools.  So sometimes there is a disconnect.  Because many of the duplex neighborhoods in DFW tend to be rentals, sometimes the neighborhoods don't look all that great.  So find 4-5 neighborhoods with duplexes for sale, take her to them on a Saturday or Sunday and see what she thinks.  You want her on board 100% with the idea.  Some wives are on board 100% and others don't want any part of it.Another trick here, is that it seems there are not a lot of full duplexes for sale with one side empty, so that can be a challenge. Either both sides have leases in place, or if one side is vacant, it was probably a rental and doesn't look real sharp.

There can always be exceptions though depending on how flexible you are to wait for the right deal and if you are flexible on where you want to live.

Good luck and best wishes....also probably a good idea to change your undercover name.
