This property is in bad shape, overgrown landscape, broken fence, exterior needing some attention.

They care about their credit scores, are easy to manage, and take good care of the buildings.

What I am saying is when you go and buy groceries, do you care what the grocery store paid for it's merchandise?

I have seen many cases where it never worked out and the people had to take the huge loss and move on with no recourse.You just have to be extremely careful.

Be careful what you put in writing,a lawyer can use it against you in a court of law.The tenant is within his legal rights to demand a receipt for rent paid and the reason is not up for debate by anyone.You must furnish a receipt within a certain time period established by your local state law.You can furnish it electronically,US Post Office mail,or in person.Also,that statement regarding possibly moving into the apartment might been seen by a judge as illegal harassment of a paying tenant.You seriously should seek legal advice from a competent attorney and let them write responses to your tenants with the correct legal language.

If you are not careful the seller will feel like it is a scam.Good luck
