I'd figure they spend less to wash than you pay to supply the feature.

Especially if you’re going with rental grade supplies.

I offered his full asking price but in addition to my "cash offer" I also offered to pain the lien, to hire movers for him, provide moving supplies, provide a 10x20 storage paid for 3 months.

Caleb, this seller wants this as his retirement plan so he wants to do seller finance so he gets a steady income for the next 15 years

Having two rentals with steady tenants and no headache factor beats 18 roommates that come and go and the rooms stay vacant for one to two months. 

In a hot market this just means it's harder to find deals because the supply is lower then the demand. 

As those additional units are absorbed, supply will catch demand, eventually.

Now I have a question how do I choose the right candidate when I'm getting several good tenants applying with good credit history good tenant history no past evictions and a good job with steady income?

In our area, there is high demand, very low inventory and very, very low supply of new construction or totally renovated homes.
