You can have two houses that are identical according to the data on paper/ virtually, but millions of dollars apart in value for infinite reasons that you just can't know without being there (level of finishes, condition, smell, same builder or different, how the property will show to potential buyers, micro-location (same sub-division or different one across the street, one has awesome views while the other doesn't, one could be on a lake while the other isn't, one could be next to gas station or on a busy street, near train tracks, a smelly factory, backing to commercial or high density multifamily, one could have settling issues with the foundation because of expansive soils while the other doesn't etc. etc. etc.).

I am currently serving in the US navy and station here in Gulfport MS.

Prime location across from the borough building and police station and what used to be the local hospital, very good drainage, great views down the big Homestead Hill from the top apartment's balcony, lots of light through the 20+ windows per apartment.My point in sharing all this is to point out that not all older residential housing structures with major deferred maintenance are at the end of their lifetime.

Car wash business is real good and if you have a problem with employees try to spend some extra money and make it full automatic car wash with pay station no need for employees 

I was stationed at Fort Bragg before I retired and help a friend flip a few homes and it was a blast.

I have a lot of land in a downtown location that different Gas Stations & Stores have offered to purchase. 

Or, installing an extensive "growler" refill station (bulk keg beer filled on-site for takeout) as an anchor attraction tenant, surrounded by other food options, especially with easy access on evening commutes, as a way to redevelop an old strip mall.

Too many reports can cause a patrol or stationed cars closer to the neighborhood.Keep an eye on the market in that neighborhood and buy or advertise to investors.

He gets a rebate of $25,000 a year on his solar panels by selling back his unused energy to the power station.If your power station does a buy back program the way Jay's does and you have power to sell back to them (no idea how to figure this out) it might be a good idea.
