Your best bet would be to call small local banks near the property and see if they will look at a reduced doc. loan where they don't focus on your W2 or credit depth. 

That said, your best bet is to get on the phone and start networking with contractors and looking at their work (go to their jobs) and finding out their pricing and what they are charging for the flips you're looking at. 

This could mean helping out a more experienced operator or identifying a coach/mentor.

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.
