Wow Becky, that's a lot--Maybe way to much for a short term goal.You don't want to end up worse off than you are now--which could happen if things don't go as you planned them.Maybe tackling the big dog on the playing field first and then revisit the other stuff a little later.The Big Dog being Domestic Violence...you were not put on this Earth to be his Punching Bag whenever he is having a bad day.Maybe you can get him to go to Domestic Violence counseling.If you split up, you can together with the courts help decide about the house, pets, kids, visitation for both of you, and child support payments, and possibly spousal support payments. 

I’ll take my peeps with their pets and bad credit scores and keep them forever.

Base lease payments on 9-10% of property value.Have leasee maintain liability insurance on property and be responsible for all interior maintenance.Leasee buys all furnishings.Smoking and pet rules apply.

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

Take a little more risk and invest at 7%, or 10%+ (public markets or even private lending)...Kinda my pet peeve I guess, but not sure why sellers want seller finance. 

We're looking to purchase a small cedar-shake cape and offer it as a pet-friendly STR fr couples.  

Originally she asked so she could convince them (since I said no) to let a rottweiler in a no pet property (that she already got without asking). 

The property was a disaster rats and pet debris everywhere.

Pet-friendly rentals command a higher rate, btw.The closer you are to the university, the higher the rents seem to be.

Adding fees for things like pets?
