When its included in a lease for real estate then the laws pertaining to residential rental security deposits in your state apply but when its separate you should have more leeway to get some additional deposit to protect you.

Being able to shuffle leads from MTR to MTR is a huge bonus and you can benefit from the economies of scale faster. 

Quote from @Kyle Schachsieck: Thank you all for the information and additional resources!

What I found was, yes it was nice have additional income, but each project seemed to always interfere.

Where is the benefit to the end buyer here? 

(Call it 20% federal and 5% state ($15k in income tax, plus the $45k in additional taxes you created.).

So additionally, that there's only 30 days to close and it eats up time for an inspector to schedule time to come.Do you allow inspections of your contracts?

Still, this is a poor time in the rental season and 1 months rent can be expected as a cost of vacancy (in addition to the cost to clean and touch up - $900) .Finally and I hope this is is the last one lol - Another tenant is moving out Jan 31st and this unit also requires a full cosmetic rehab.

But almost zero percent of NOD owners can make it through the selling / moving out process go get this benefit. 

It will familiarize you with the basic terminology and benefits.
