Look at all of the losses you can count against your rental income.Now look at line 18.Line 18 is usually:(Value of your property) - (Land value) / 27.5 years.

For example, maybe you will get to 10, 20, 30 houses and then find an owner who has a large portfolio and all of a sudden you are at a high door count and now need to hire, need to build your policy binder, and all the other stuff that comes with running a business.

I was in a leased building, counting on a hand-shake deal to buy the property in the future.

We have the highest Realtor count per capita is the U.S.

I've invested in 6 properties and counting with them.

@Cameron Moore I knew I could count on you for a legit answer.

If it's net positive, then make sure to do it up to code, etc so the finished square space can count.

Brewerytown and East Passyunk could also be worth exploring.Big projects like Bellwether can boost neighborhoods, but they often take time to show results, so don’t count on them as a main factor.

Went over budget and still counting.  

I'm not counting those since I don't manage them, but I typically avoid cities and states with laws antagonistic to landlords.
