In a gun friendly state, find a local gun club, have someone there help you shoot them, then decide if you are going to sell them.As for the ammo, if it is factory ammo, and looks like it has stayed dry, it is good for decades, again, have someone from your local gun club look at it.

Large flat walls are cheaper than small areas with lots of cuts & corners.It will take a small crew about 7-10 days to hang drywall, tape and mud, then let it dry a day or two, then sand, mud again, dry again and sand again, finish and clean up.

I have an application in front of me now where a prior landlord gave her a bad report because the vertical blinds were missing and an "excessive carpet cleaning" charge on move out.

I usually try to workout at least 4 times a week so this can save me about 4 hours a week in excess gym time.

Everything else has to be refreshed : Floors (carpeted, heavily spoiled and cat urine odor) Ceilings dry-wallWalls dry-wallElectrical is out of date (knot and tube all over, electrical panel needs replacement) Risks: Sanitization (cat urine smell, potential for pest problems)Structural integrity not checked (unable to check in a timely fashion due to deadline)Evidence of water damage on main floor ceiling, extent of damages unknownNo smell of mold in basement but knowing the city history of flooding, this is uncertainPlumbing looks recent but it was hard to be absolutely sure of this assertionThe reason I decided against in the end : too many unknowns.

They apologized and said to use the dehumidifier and air blower until it dried.

Keeping it dry, safe, usable and not too scary is the plan.

Dry rot too.

A handyman landlord working with minimal help can do good work in these places, stay on top of things, and keep perhaps ten of these tight little ships running with practically zero outside labor costs eating into his profits or excessive time commitments, while he does modest, leisurely little spec rehabs and occasionally larger live-in flips anywhere he finds deals, accelerating his timeline to  pay off his street of moneymakers. 

Made me feel like a smaller scaled NYC (without the excess lights of Times Square).
