I would like to know more about ways to use OPM  The only way to determine if the home is going to cost you a lot down the road is by determining the age of the mechanical systems & if the structure of the home is sound. 

For a rule of thumb, replacing a commercial boiler can range anywhere from $20k to $150k, depending on the size, age, and efficiency.

Quote from @Chaliyah Penick: I have a relative that is up in age and no longer able to afford the mortgage and are falling behind. 

My main goal is it be able to retire at age 40 from my main job and work entirely on my real estate portfolio.

@Andreas Mathews,Good for you at looking to make a change no matter the age.

Hi everyone,I’ve been fortunate enough to acquire 32 rental properties by the age of 30.

These requirements are solid, keep them: Application: Everyone aged 18 or older must complete an application.

I think another factor here in determining whether its a good investment is your age and your goals. 

Quote from @Travis Smith: Age 56 and retiring from farming and I’ve been very good at avoiding income taxes with depreciation and business expenses.  

I'm an independent agent here in AR and I write a lot of rental property, with ~6 preferred markets and if the properties have some issues, age, claim history etc.
