To add on to the last post, also make sure the seller brings (or credits) you with the security deposit(s) and any pro-rated rent for the current month that you close.Regarding lead, I'm not sure about your state, but in MD, rentals must have lead certificates.

Can I list the higher rent but then agree to a monthly credit for her managing the property or is it easier to have her manage building for free in exchange for rent?

However, after running the credit checks we found out that our credit scores are about 100 points different.

@Tony Mai Have you tried credit unions?

Our primary house is a fixer upper that I have been fixing little by little myself and over time that run into 25k credit card debt.

But if they have bad credit or eviction you can deny regardless of sec 8 qualifications as long as you deny every applicant with bad credit or a eviction You can turn away Sec 8 on the grounds that your properties do not qualify as you are not registered or had approval from the program. 

Some tenants may have some money but not the credit to qualify for a loan. 

When you guys file your annual taxes this amount will be credited to what you owe, or refunded if it is more than you owe.

Now the prospective tenant claims Trans Union is not allowing their credit report to be released.

I wanted to propose taking the property off their hands as follows: I'll bring the mortgage current, which will save their credit.
