Remodeled: upstairs unit with new appliances, paint, complete bathroom remodel, fixed plumbing, refinished flooring.

Hi All, my question is I have a contract on selling a home of which I had to complete many things like a new roof, HVAC, and plumbing.

New electrical, new plumbing, new HVAC, etc. in the past five years?

I don’t know if I should lean towards learning all the trades about homes, As in electrical plumbing carpentry or just get a real estate license to get access to all of the listings?

Water heater, AC Unit, Electrical, Plumbing if possible. 4.

@Tony Gatto Check the plumbing, hot water heater, and siding to see if there are any issues.

Maybe we take off some drywall so they can see plumbing and electric and make a couple tweaks and we're good.
