The seller, while very motivated, is also out of patience, and is ready to kill the deal.In an attempt to keep it alive, a dialog with my agent led to permission from the seller  "to do whatever it takes to put this deal together"This was in regards to altering the property to meet the requirements of the lender, to be clear.As it stands, we close in a week.

He repeatedly trespassed on my property (documented with pictures, etc.) and I called the police on him when he refused to move his guests vehicles out of my driveway that were parked there without my permission when he was throwing a party.

If permissible, will you do the work yourself or contract it out?  

In Ohio, the law states you cannot market a house for sale that you don't own without written permission from the Seller.

I realize all appraisers are different, but I feel more comfortable getting a professional ( hopefully ) opinion.If necessary to renovate interiors before refinance, is there a way to do it while they are there with their permission before their leases ends? 

@Patrick Mcgowen,I had permission/permits for nothing because a mobile home manufactured etc is not real estate its personal property hince the repo not foreclosure I did at least tell the park manager I will be rehabbing the mobile home.In some cases because I do a few mobile/manufactured/modular home investments I typically have the home moved to a unrestricted lot and placed on foundation which then increases value.

@Mike M - "Collections will probably not talk to you unless the owner provides written permission."

The HOA requires him to get my written permission for many of them. 

While it may be legally permissible it is unethical.

@Jonathan Beasley Your options are limited by a few factors:Is it legally permissible to implement a RUBS program in your market?
