Won't be able to do roof 25 year life span, appliances and hot water heater 12 year life span, hvac 20 year life span, bath and kitchen remodel 20 year life span, etc.

They will take care of the master plumber's permit and work to disconnect and cap sewer and water lines as well as electrical panel removal and gas line disconnects. 

HUD will not pay to turn the utilities/water on for the home inspection so be prepared to pay for that up front.

I was doing some reorganizing of the basement in my primary home when I noticed just the smallest amount of water on the concrete floor.

My capex budget includes roofs 25 year life span, floors 10 year life span, appliances and hot water heater 12 year life span, hvac 20 year life span, bath and kitchen remodel 20 year life span, etc.

I make sure to verify that the final water bill is paid before sending it out since in Iowa it follows the property and not the person.
