Are you asking about buying this lot and putting an actual operating storage facility on it?  

If you value this property with a 10% cap rate with $78,9884 operating income, it puts the value at $789,840.

Ultimately, it makes little sense to sell the house you're in now for 850k if you're going to have to turn around and buy a house for you to live in at say 750k to 850k because thats where the price point is in your area for a home that you will be satisfied with.Your best bet then would be to stay where you're at and get a heloc and use that bo buy the 280k rental property. 

It really just depends on how much equity is still left after the cash-out that you already did.It sounds like your best bet would be to get a HELOC and use the remaining equity to buy another deal.

Do you have the EIN, bank account, and Operating Agreement?

The property is operating at a loss & the tenant is "soft threatening" you every renewal?

They operate in all 50 states, are very investor friendly & have saved me an average of 30-50% on my coverage.

Realize, too, that fix and flippers tend to have cheap sources for this sort of thing and would not pay anywhere near what a homeowner would pay a kitchen fixing company.Your best bet may be to donate the cabinets and appliances to Habitat for Humanity.

Hard to get excited about $480 per month minus operating expenses (assuming I understood correctly)...unless of course you know you can expand as many of your expenses will stay flat while you revenue will clearly go up. 

I know there is some glitz and glamor to "being your own boss", but as a new agent there is so much knowledge that needs to be soaked up, and applied on top of the daily "run the business"/operations items, that it can be overwhelming.
