Fannie Mae has a requirement that if you want to use the rental income from the non occupied units, that you MUST have a current housing expense which means you cannot live rent free.

I wouldnt, so long as you have your requirements laid out - they should be able to know if it is even worth applying.

It is pretty easy to keep it fully occupied but it does mean I turn away a ton of people who want a lease that doesn't quite fit my requirements. 

There were several mistakes made on my tax returns that I pointed out, which required going back and forth with their tax preparers, and asking repeatedly to cut to the chase and have a phone call.

@Kyle Trotman If you purchased with a hard money loan conventional lenders will require extensive seasoning to utilize the new appraised value for cash out. 

Often it's a really easy fix or operator error that does not require a pro.

High credit scores and low DTI are often required…and these take much longer than I first thought…Navy might take 45 days to get through the gauntlet.  

If the latter, simply give her the notice required (eg 30 or 60 days) that she needs to move. 

But, they still require time and effort.

Most new construction deals require you to give up to a 10-year warranty on some items while most fix and flips come with very little extended liability after the sale excluding gross negligence which is not stopped by an LLC in any case.
