As others have said, it's probably best to utilize your money buying one or two multi-unit buildings. 

@Jon S, most of the issues I've seen boils down to HOA / code enforcement / underestimation of utility usage.  

We were able to talk with the seller and the PM and analyze the deal pretty extensively and just submitted our offer yesterday.

But above comment is probably right about tragedy of the commons effect on "everyone's laundry area" which can be a cleaning and utility cost issue and even vagrant or misuse issues..

We have a standard contract, utilize the money for a project and then pay it back in 12 months or sooner (like if a flip sells sooner than 12 months).  

But  I have the lanldords policy at 300k per occurrence and don't have the extension from the personal to the rentals (which you may want to have professionally examined to make sure that is the case).

Cashflow is the number you come up with after paying the mortgage (PITI) and also accounting for expenses like vacancy, capex, maintainence, utilities and management.

It's incredibly useful, an amazing program to utilize.

As an extension to this question, should inflation in be included in any of these calculations?

We will keep you posted on the progress of the extension as the process moves forward."
