He claimed if he didn't get the money he could not buy supplies to complete the job, which would be done in a week(I knew this wasn't true). 

Housing supply is the other function, and my view as rates increase so does inventory in markets that are coming up to pre-pandemic levels and the inverse in the one's that are decreasing. 

Personally when I’m working on a project time is money and I don’t have the ability to wait around to get supplies.

Do you think that was because of supply & demand, and/or the rate of inflation at the time? 

If you supply the machines, I recommend increasing rent $100 or so to compensate for the purchase and maintenance.

We know supply is a big issue with low inventory across the whole country.

I will be living in the guest house, while renting out the main.Both units are without washer and dryer units, my question is, do I supply them in the main house; or let potential tenants figure that one out?

Actually buying these apartments and not the current supply is a good opportunity.

I am the boots on the ground and provide all of the time and my partners supply the money.
