It turned out to be a disaster after the rain uncovered way more than we all thought.

All of these problems you have uncovered is a bad sign, most likely they are others lurking around.

After it’s firmly under contract, I’d recommend taking an experienced CRE investor through it to try to help uncover everything that could go wrong.

Issues like peeling paint, broken windows, outlets/light switches uncovered would not pass inspection. 

Hi, I'd like to start looking into some turnkey companies that specialise in residential properties nation-wide and preferably ones that handle everything.

Apply the deposit and refund the remainder or charge them for any uncovered expenses.

But back to original comment, if things are moving forward, I would lay out that you would love to stay involved in the deal with an ownership stake for uncovering the deal, and then let the conversation take it from there.

At some point you’ll uncover a good one.

One option might be to pay to have it found and uncovered and then on closing hold back the funds that equals the cost of that service.  

In my leases I clearly write and explain to tenants that we will remediate any issues uncovered in the 1st 30 days at our own expense.
