We have been getting notices from section 8 that say they cant accept the rent amounts on stabilized renewal leases.

The price range for my purchases will be between 40000 and 80000 (I live in central Illinois) and I've noticed some homes in this range are already rehabbed and some need rehabbing.

if you are near the end of the lease for the tenant you can list it with seller notes saying currently occupied and will be delivered vacant by end of escrow and make sure to give the proper notice to the tenant that you will not be renewing it

I did so when I accepted guests with several 5 stars and noticed they are not the 5 stars type but previous guests have been too nice obviously.

- What level of rent decreases can you sustain if new units become available?

Tell her what the rent is and if she is not willing to pay you give notice to non renew the lease.

The value of money decreases. 

So if it were me I would gracefully accept his notice and allow him out of the lease with 30 days notice 

I have noticed other sold prices from December/18 to be below assessed value and sold homes from earlier in 2018 to be above assessed value. 

This would make your property value decrease and be less marketable.
