After a lot of thorough conversations, I have decided that I will be renting the house to my tattoo artist.

Yes if you don’t have mortgage history this validates your primary house expense 

If so, I'd start bringing a tape with me to look at houses if the problem is you can not visualize 30 sq ft of granite.

I have never had the IRS redeem in all the years I have been buying court house steps.. and if they do they have to pay you statatory interest but you are out any rehab you did to it.. so have to be careful there you may just have to hold it 6 months is all..

Assuming it is a residential property, it will be roughly 3.64% per year of the actual house/condo/townhouse/etc value (not land)

I can't imagine one of these fitting into a standard house, unless it was a ranch with a near direct shot to the bathroom.

I am interested in purchasing a home that has been recently known as a squatter house. 

Any travel nurse is a brother or sister in my field, so my plan is to make sure their housing is everything they could imagine in comfort and necessity be met.  

After freshening it up and getting it rent-ready, I was able to list it two weeks ago.I've had a decent amount of interest, two open house showings with about 6-8 different potential tenants/couples.

I was able to call them and give them a run down of my progress on a project and they were happy to give advice.They are just people and most don't want to cause issues for owners.
