Given what I know it needs without even seeing it, though (new roof, fascia repairs, animal control, new boilers, lead and asbestos remediation, oil tank removal--and that's without knowing anything about it structurally or cosmetically on the inside), I'm guessing I would have to put in roughly $100k in rehab.

I signed up with a commission-only online brokerage in order to keep fees low.

The online sale is about to end and the current bid is still less than 70K.

Maintenance of of the property (including landscaping), proper termination of lease, adding/removing tenants or animals, dealing with damages and deposits, and more. 

Reinforce changes to the property aren't allowed and state it in your lease (no painting, wall building, wall moving, etc), talk about specific lease restrictions (e.g. no pools and trampolines, limits to guests, animals) on lease signing. 

Fellow Investors, Does anyone have any experience with the following online property management software?

Recently my wife and I were looking at listings online and saw a mobile home for sale.

Pay particular attention to Page 12 where it explicitly defines what type of animals are allowed.

Zillow and other online sites are not the place to find deals.

I have seen tons of these online, many of them are free modifiable templates with verbiage that you can change out.
