Both these 2 are not easy to do, and typically take expertise, experience and or capital.  

On top of that, FHA has very strict and particular rules around income.

.: And how would you enforce that ruling Brian?

Asking in the correct forum will get a better response.Read the RULES!

Based in Tampa, I have a lot of knowledge in Pinellas County rules and regulations as well as best practices/highest returns. 

Also have made it easy to see if you offered a certain amount, or changed your rehab budget, how that would affect your return. 

If you're the only one in your company, this may not be necessary since you set the rules.

The most important rule is to have the cash flow of the new property be able to pay all its expenses, mortgage, AND the line of credit back.

But even if you want to do large deals, you need comparable reps.Technology has made it easy to "analyze" deals.

Quote from @Jeff Roth:Monthly rents for mid-term rentals are about 20% (+/-) higher than unfurnished similar long-term rentals.I would not base the income potential for a MTR on a rule of thumb.
