@Polat CaglayanI've never seen a formula but here is a general rule of thumb for multifamily:The class of an apartment refers to the quality of the building, which can be determined by a number of factors, including age, location, and condition: Class A: These are the highest quality apartments, typically built within the last 15 years.

Quote from @James Hampton: That's a bad practice to follow.If an occupant is not named on the lease, you may have difficulty enforcing rules or evicting them.

So if I understand this correctly, by qualifying to extend the 5 year rule to 10 yrs, $250k if single or $500k if married of proceeds from this sale would be exempt from capital gains?

There is no such absolute rule or mandate for REI - it is up to you on your comfort level with your cash flow versus total investment versus appreciation potential.If I followed that rule, I would have missed out on a LOT of great opportunities over the years.We bought a house in Jones Valley in 2017 with negative cash flow - why? 

Focus on buying below market value, running numbers first (cash flow, 1% rule), and choosing a landlord-friendly location with job growth.

In a very loose rule-of-thumb estimate, your Net Income (revenue minus expense) may be about 50~60% of the gross revenue.
