If you buy a property on your own you must substantially improve.

See the YouTube link below.

You raise $5K/door (or more) upfront to address deferred maintenance and value-add improvements.

I luckily stumbled across BP by complete accident as a commercial advertisement on YouTube while I was listening to a stock market podcast. 

In the warranty deed that was executed the seller swore to defend my right and title to the Property and all improvements thereon against all others.

I have some You Tube educational videos you can check out.

And to expand a little further on Frank's cap-x comment, during the last recession there were plenty of apartments with 20% vacancy or more, simply because the ownership didn't have the resources to do the capital improvements necessary to attract tenants. 

Also sounds like you might not have the capital for a major improvement if you buy something that needs work?  

Take care of the property and focus on credit improvement. 

We'll likely throw money at it once someone moves out and we need to improve it to increase rents yet again.
