There are deals everywhere, but AZ seems to be appreciating through the roof without an end in sight.

They did a nice job a replacing a roof and gutters and they also do siding.https://winterhillgeneralcontr...

For example, i) check and send a picture of the electrical panel, ii) gather info about the age of main features / appliances (e.g. roof, water heater, etc.), ...  

Got a crazy story out of it though… through some sort of miscommunication, the roofing sub-contractor replaced the roof on the wrong house!

My Roofing and Remodeling company lent my Property Acquisition Company the money from a business line of credit for both the purchase price and the rehab costs.

The roof and furnace are both brand new and the listing price is $89,900.00. 

New plumbing , roof , electrical etc.

Other side needs rehab and roof...so yes something short term.

Can I write off the expenses of a new roof and a driveway repair during a room "house-hack" where it is a primary residence? 

Cash flow is the money you have left AFTER paying all expenses, which includes setting aside funds for future maintenance, capex (roof, carpet, furnace, driveway, and other big expenses), vacancies, property management, etc.
