Central HVAC units do not count as appliances, only window units.

I passes on a duplex after seeing one tenant blast the heater with all the windows open. 

I also thought it'd be good to get first-hand experience of how much effort certain things were to do.I've already done a few things in the past like:- Tearing out carpet and replacing the entire floor with wood laminate- Painting an entire interior- Painting kitchen cabinets- Resurfacing a laminate countertop with concrete- Replaced a toiletI'd like to learn a bit more, like:- laying tile- replacing a window- replacing a light fixture / switch- potentially retiling a portion of a roofWhile I don't see myself doing all these things for future investments, I think that having a good understanding of what it takes to do each one gives me good leverage and experience when negotiating with contractors.

I found two properties that had windows boarded up and that were neglected, how can I find the owners information to make a deal?

The bank has held the property for 7 months and is asking way too much for the house given the work that needs to be done to it.The situation: First and foremost the original wood siding is rotting all along the base, under some windows, a bit under a gable, and a few random spots so it NEEDS to be replaced and I'd prefer to replace all the windows at the same since they're single pane and will need to be replaced eventually.  

Upgraded the kitchen, bathrooms, and windows.

Renovation included new roof, windows, exterior paint, landscaping, gutters, flooring, interior paint, light fixtures, switches, kitchen remodel, bathroom remodel, washer/dryer and window coverings.

I might open up the windows on a breezy day if they've been closed up awhile, but that is it. 

The windows and door is all boarded up.

The exterior has been freshly painted, it has new windows and doors.
