my biggest profit for just buy and hold was land as well.. we bought 3.5 acres in Sonoma county CA for 27k  in 96 ish  sold in 2000 for 2.2 mil. paid tax's of 300 a year and mowed it about every 3 years for 500 bucks.. same thing as you .. unbuildable acreage but Indians bought the land next to us and built the largest indian gaming facility in CA

Henry what type of development  another Storage facility ???  

The law does require you to have an interactive discussion with her but - again - you're renting an apartment not a bike storage facility. 

My self-storage facility sometimes gets 5-6 calls in a month!

This would work for many different business models that have an owners quarters such as some storage facilities or car washes.

If one of those guys relapses and cooks meth it will be really bad and not only will everyone have to leave but you won’t ever be able to sell the place atleast not for fair market values .

Can anyone give me resources about purchasing a storage facility in the DC area?

I had to replace a $9,000 furnace, a water heater, and a couple of appliances, and I am about to spend another $10,000 on excavation for my storage facility.

My W2 income is >$550k/year, if I build an RV/Boat storage facility, will my storage business expenses/losses be able to reduce my W2 taxable income? 

Less surprises and less "cooks in the kitchen" over however many years.
