CAP Rate — Is It Really the Most Important Factor in Multifamily Investing?

Question

When evaluating a commercial multifamily property, many investors laser-focus on the CAP rate — but is it really the #1 factor?

The truth is, CAP rate is just one piece of the puzzle. Here’s what you should weigh alongside it:

Location – Markets with strong job growth, population increases, and renter demand often outperform.

Rent Growth Potential – Can you raise rents through market trends or value-add improvements?

Property Condition – Deferred maintenance can kill returns fast. Inspect thoroughly.

Value-Add Opportunity – Underperforming assets with room for upgrades can significantly boost NOI and future value.

Tenant Stability – Solid, paying tenants are worth more than a high CAP rate with shaky occupancy.

Financing Terms – Great debt can sometimes outperform a “better” CAP rate on paper.

Remember: A good deal isn’t just about today’s CAP — it’s about tomorrow’s potential.

Good evening, Karl,

I would recommend looking at more than one data metric. Cap rates can certainly provide insight, but the challenge is ensuring that cap rates extracted from comparable properties are treating expenses similar to that of a property one is comparing them to. One example is some cap rates may include replacement reserves as an expense, while others may not have any replacement reserves in the cap rate. Using a cap rate that includes reserves and applying it to a property that does not include reserves can give an inaccurate indicator of value. That is just one example of why caution is necessary when using cap rates to evaluate a property.

If buying a property to hold as a long term rental, you also want to look at how many available units are currently on the market, and estimate the market absorption rate to determine how many months of inventory are available. The property someone is purchasing for long term rental will be competing with these other properties, and the property may or may not capture its market share. Furthermore, if there is more supply of units than demand, that is going to result in downward pressure to rental rates, whereas if there is a shortage of supply with potentially pent up demand, that is going to result in upward pressure on rental rates.

There are many factors to consider when evaluating a potential investment property purchase, and it’s important to analyze available data to make an informed decision without crossing the line into analysis paralysis.

@Karl Markarian one of the best talks and viewpoints on this exact topic I've hears was from Ashley Wilson at BP con in 2022 and her talk "the caprate con". She into into exactly what you are discussing above and so much more. biggest thing I took away was the fact that people obsessed with cap-rates oftentimes don't understand the underlying "variability" in them. honestly if anyone is too hung up on caprates its a pretty decent sign they are somewhat "unsophisticated" from my experience. To your point they lack the ability to zoom out and see the asset as a whole.

You can still have a decent cap and no cash flow. So yes, cap rate is a good metric for value, but it doesn't mean you will make money immediately. Just as one metric. Location, condition, etc to take into consideration

@Michael K Gallagher Thanks Michael - That's been exactly my viewpoint for years.

Just because it's a 4.5 CAP today doesn't mean you won't reach higher CAPs in year two and beyond. The real focus should be on the asset's future value and potential — not just the immediate return

I just want to know market rent!

Karl Markarian · Answer

Totally agree with you William. Cap rates are helpful, but they can definitely lead you down the wrong path if you don't dig into how they're calculated. I’ve seen that replacement reserve issue pop up more than once, and it can really throw off your valuation if you’re not careful.

You're spot on about supply and demand too, especially for long-term rentals, it’s not just about the numbers today, but also what the market is likely to do in the next few years. Appreciate you jumping in with this perspective.
