The Investor’s Guide to Pulling Realistic Rental Comps

by |

How do you effectively find and evaluate rental comps?

Rental comps are just as important as sales comps when looking at buying a property. Knowing how to find them and accurately assess them will directly impact whether you’re able to achieve profitable deals.

This is true even if you are wholesaling or rehabbing and flipping houses versus acquiring buy and hold units for yourself. This is because you need to know the real resale potential and should retain renting as an alternative exit option if your plan A doesn’t work out.

Unfortunately, this is where many investors are blowing deals—and their financial futures along with them. Too often, they accept what a current landlord, wholesaler, or real estate agent tells them. Then they get stuck and wind up with a deadweight deal that negatively cash flows every month.

How to Invest in Real Estate While Working a Full-Time Job

Many investors think that they need to quit their job to get started in real estate. Not true! Many investors successfully build large portfolios over the years while enjoying the stability of their full-time job.

Features to Compare When Pulling Comps

You’ll be looking at many of the same features and factors for rentals as sales comps.

They include:

  • Living area square footage
  • View
  • Bedroom and bathroom count
  • Architectural style
  • Age
  • Property condition
  • Special features like pools
  • Parking spaces
  • Location

Rentals can also be impacted by a wider variety of factors, especially amenities like nearby gyms, pet spas, restaurants, etc.

Other factors to consider with rentals may include the application process, upfront money required, seasonal fluctuations, inclusions like utilities and wifi, and special concessions and offers like free rent.

Pulling Quick Rental Comps Online

There are lots of online tools for pulling rough comps fast.

Some of these include:

  • Trulia
  • Hotpads
  • Craigslist
  • Zillow has a free neat tool for instantly getting a rough estimate of area rents and showing you where prices fall within the whole market. A paid plan offers a deeper analysis. 

Zillow has a rent “Zestimate” for formulating a rent rate. It can be fairly close, give or take.

Note that you’ve really got to dig into the data if you want accurate answers. Sometimes your first answers can be a bit inflated, often caused by overpriced rental listings that no one is willing to pay for. These tools also do not take into consideration the types of renovations done to a property. Days on market need to be considered as well!

For example, if a comparable property across the street from yours is asking $1,300 a month and it has been on the market 90 days, then that is a good indication the market is not willing to pay that. The market will always let you know whether or not something is too high. The market (renters) provide the best feedback. It is also smart to look out for the number of rentals that are being advertised. If there are too many, landlords are going to have to fight hard for any tenants and may have to come down a lot by making concessions.

There can be a huge difference between asking rents and actual rents. One house might be asking $1,500 a month. An identical unit next door could have just leased for $800. It’s hard to know online because this data isn’t provided like actual recorded sales comps.

Getting Comps Offline

Look to local professionals who are active in the market for better data. Think property management companies. Find a company that manages several rentals in the neighborhood you target. They will give you a solid rate that they believe they can rent it for.

Get in the trenches. Spend time in the neighborhood where you plan to acquire, and ask folks how much they are paying in rent, if they’d move into your property for $X, and what they think about the property.


Being able to get and evaluate rental comps is vital for all investors. Don’t get caught with longer vacancies by failing to do your own due diligence on rents and rental demand.

    Zillow margin of “error” on rent Zestimates can be quite big – in some areas we researched it can be 10% optimistic, while in other areas it can be 10% pessimistic. Same with Rentometer – even wilder aberrations as rentometer looks only at radius, ignoring spilling into different neighborhoods/subdivision or crossing major roads (thus including area of significant difference).
    Take them both with a grain of salt and try to confirm with at least another source of rent estimates (MLS lease CMA, Rentrange,
    We used to consider the average of multiple sources – but lately, due to a glut of active rentals in an environment of raising prices, with the associated raising RE taxes (at least in TX), I consider the lowest rent estimate in my investment calculations.

      I use rentomenter pro. My first stept is to look at the median and average rent along with sample size seem reasonable. Step 2, I look at the individual comps provided by the website. Step 3, I try to narrow down my search by only looking at SFR or apartments, or duplexes if that’s the property I have. Step 4 is to narrow down looking at apples to apples, ie within the last 12 months, close proximity, like type property. The hardest factor to determine is the condition of the rentals comps. It’s hard to gauge that.

    This is really very true thing, it really happens many time with me too. I am also in the same business, some people left so much margin for their own benefits, but we need to understand how much price they are offering and is that price is acceptable or not. i found one place, who gave properties, flats and apartments in right price, which is acceptable. me also find good deals over there
