As long as you have proof of mailing you're okay on the time (not when she receives)  If you end up spending less to clean then you may have to refund some of the cost. 

Your costs are fixed and so you probably can't provide discount financing. 

@Matthew Crane the answer is - maybeAt best, you can claim some of these indirect costs as startup costs. 

My question is, if we buy the home using a conventional personal loan while we househack, what would the costs and process look like of transferring the house and the loan over to an LLC?

In my state that would be an expensive change as I would be paying state transfer tax on the move along with other costs plus I would need to consider whether I wanted to buy title insurance on the property for the new LLC.

We expect to have holding costs of $15k to get through the off season and the condo is pretty updated so we would only be spending $10k in renovations (updating the bathroom and then finishes in the remaining rooms).

That's three months of mortgage and utilities, the cost of flooring, and the cost of painting.

Mortgage Costs UP - There will now be folks with a higher risk obtaining more debt, a lot more debt.

That is not reflected in the lawsuits related to this issue.You make no mention of the escrow costs or tax implications or transfer taxes or scrutiny that is involved with a deed back.

Eg if owning a house for the mortgage, insurance and taxes alone would cost you over $3000 a month (mortgage alone on a 25 year amortization for $500K is $3000 a month, goes down to $2700 on a 30 yr mortgage).
