Screw the sheet rock one, paint it, and use a strong caulk or liquid nails(may be to strong if you ever need to take it back off) to hold the sink back up(or use the existing screws) and call it a day. 99/100 people will probably never notice that piece. 

Many people give up the goal  right here turn around or back up and forget the goal, and say it's impossible. 

I have a neighbor that I have talked to over the years who lost his job and needs to sell his house quick he is 4 payments be hide but this is not the first time and he has no job to get caught back up. he owes around 40k and wanted to list it at 60k I offered 50k for it he shot back with a price of 55k. which is my max offer price.

If I keep my debt minimal, bring my credit score back up a few points with regular payments, and maintain my income would lenders consider this scenario?

What happens if the deal goes upside down, what if he stops showing up, what if you stop paying, what if he has other work and puts yours on the back burner because he can't get fired?

May need to put this on the back burner for a few years and see how this tiny home market shapes out...

I'm considering holding it as a rental until the Spring when the market picks back up. 

One of those lessons is that when you get knocked down in the ring you have to get back up in order to have any success at all. the school of hard knocks is a very effective teacher but she is high priced.

You can also expect to be a backup offer, again firm with no later-renegotiating, that looks favourable if the other party tries to lower the price after signing the contract.

The 4th burner on the stove broke.
