If I can pay it off in a 7 years I’m fine.

I would buy something closer to turn key if you can, even if you pay up, because it will reduce the work you have to do and figure out as a new large-scale investor.

If it pays for itself, it provides you with a "free" place to live during the off-season.

Must pay well, she door dashes breakfast, lunch, dinner like clockwork.

Unless the borrower is self employed and takes a lot of expenses to show lower income on their returns then it usually makes sense to pay a couple thousand a year in higher interest (you can pay like 4,000 a year in additional interest for DSCR if you are saving 30+k on your tax bill kind of math lol)

Most of the buyers are just regular folks looking for a home, so they are not at all thinking about cap rates. 

She does not own the lot and pays like $150 per month lot rent.

The rental income from the first home will pay for the mortgage/monthly costs.  

@Robert Brock, I guess my advice is not really any different than I would say to someone wanting to be a residential wholesaler: you need to add value to the transaction.Often times, having the deal tied up is the value, but more often then not, in my limited experience with commercial wholesalers and residential, the wholesaler has no idea what someone will actually pay, so they tie up a deal at too high a price and then add their fee that turns a bad investment into a horrible investment. 

That is good but there are fewer folks looking to spend over $1000 a night on a place.This all looks like a problem waiting to happen IMHO.
