There's lots of fresh/relevant data out there as well. 

INSIDE KITCHEN CABINETS HAVE BEEN PAINTED A FRESH WHITE OVER OLD OAK CABINETS FOR AN UPDATED LOOK .

Once expenses are cut down and the building is as efficient as is feasible (LED lights, efficient furnaces, etc), then you can look at making improvements that are pleasing to the eye.Also, instead of renting out the lot to a trucking company, maybe your tenants would be interested in having storage units there that they can rent out?

My future goals are to own 250 units in multifamily/apartments and to own 200 storage units.

If there is not any wood structural members, and if the fire took place beyond the 28-day curing time on concrete (when is fresh), the foundation should be intact. 

This would give more counter top space and cabinet storage and improve function.

We started out supplying both washer and dryer as fresh newbies to the rental game.

They sold very quickly.Did the pole barns act as garage space for parking their cars, or simply storage/workshop space for tenants? 

I purchased the property in august 2019, home inspection was good and pretty much everything wrong with the building(multifamily) was taken care of and fixed by licensed contractors before closing as part of the deal.I just evicted a tenant for non payment of rent, who decided to move out right before he was served by the sheriff, he changed the locks to make sure I couldnt get in, stopped paying rent, then I started hearing sawing, hammering and power tools and oh boy.. he removed walls, railings and insulation from the barn attic storage area he had that's attached to the apartment, he apparently replaced the bathtub surround and put a new one on but didn't seal it to the tub... and continued to take showers, I just had new tenants move into the apartment below this trouble apartment and there is now wet ceiling in there kitchen right under this said bathtub...this was not damaged or wet when I showed them the apartment which was the week he was moving, I heard him just running water for a couple hours one day, Im sure he did this intentionally to cause damage.

Fresh off the presses!
