We sold our house recently.

Is it as simple as contract the new home with a move in date within 30 days, and write the lease back agreement with the current owners separately therefore leaving it still as a primary residence? 

Though the current housing market conditions can influence the cost-effectiveness of buying versus building. 

Hello, I live in California Sacramento, recently bought a primary house which I plan to do house hacking.

May require permtis and consultants depending on the scope $70-$100 per sq ftStuds out/Addition: This involves taking the existing house down to the framing.

The main part of house is renovated and rented out.

Also the title company said I had to pay all the water bills on all four houses for bills thru the close of escrow date.

I bought a house in a Lennar subdivision to turn it into a rental the following year. 

They definitely have overlays but they keep all of the loans in house including owner occupant mortgages.

In recent years, we've often heard predictions about a housing market crash.
