She had that job before we got married though…If the property's suitability as the taxpayer's principal residence materially changes, then it might qualify for the unforeseen circumstance.

at the least its added to the principal at the worse they start foreclosure.

When you sit down with the seller and you agree on the monthly amount due…does that monthly amount due consist of PITI or just principal? 

Even if we do a max out cash refi our personal budget is still well within our means, but since we are also trying to pay down the principal as quick as possible I'm thinking of the HELOC too. 

They have to pay capital gains tax, and depreciation recapture, on the appropriate portions of all principal received....interest is taxed as interest income.

I had $75k in a Roth 401(k), about $80k equity in my principal residence (pending a new appraisal), and only about $12k in savings (my wife just got her job about 3 months ago and was in college for 2 years prior to that, so things were pretty tight.)

My current STR is making a 35% cash on cash return, and has exceeded 80% returns over the last 2 years if I factor in appreciation and principal paydown.
