It is in the rental agreement that they carry it, as it give me protections and recourse if their pet does extensive damage.

Hutchinson bundling your homes into one "blanket" loan carries some benefits (and draw backs) but the rate is not one of them. 

If they pay, they are in compliance and you carry on with your lease agreement.

The house will carry itself if not even cashflow a bit.

I carry as little CC debt as possible, I try to keep it at zero.

It was an 1800 SF colonial in much better condition, didn't need new HVAC, but did have a big $25,000 foundation hit.With that said, what are you carrying for your rehab costs? 

If you have a history of late payments, carrying a balance, or have just never held a credit card before and are unfamiliar with the temptations of having an easily accessible $5,000 sitting around can be, I would highly recommend you sit on the sidelines.

However, @Mike D'Arrigo makes a good point with needing 20 homes that will carry you well over the 10 mortgage conventional max.The net result is that if I were in your shoes I'd be evaluating what a good first investment is for the $100K. 

I'm curious how much of an adjustment do you make for that, knowing your exit strategy has to be to keep it as a rental or sell it to a cash buyer or carry the contract yourself?
