My Ranges will cost only about $500 brand new (I just bought a new one today).I don't think the one shoe fits all works for $100k multi-family buildings in low income areas versus high Multi-Million Dollar multi-family buildings in dense and desirable areas where you can command high income.The two kinds of investments need different calculations and strategies.I absolutely know these differences because of my other friends that decided to invest in non-Major Metro areas outside of my Area.

It has a large covered pea gravel patio on the back and a separate storage building to house yard tools and equipment. 

Pay for 30 or 60 days of storage rent and throw a combo lock on the unit.

Currently I have a couple single families, a duplex, and a small storage facility that generate a good income. 

I store spare appliances in a storage building. 

In your shoes, I would do a nominal $35-$50 per month for a 3-5 month lease.

It's something 3 generations of my family has done and I think it's finally time to fill those shoes. 

UST -> underground storage tank...

Rent the house-$600/mo, rent the pole barn for storage-perhaps 10 boats at $300 for the season, rent  the land-$2250 for a year, put up a billboard as the property is next to a county highway with good traffic.  

Also if you think house hacking is the way to go, then how, if you were in my shoes would you proceed with doing so.
