Not familiar with Iron Mountain, but sounds like you've found your niche markets...Outside of financing, what other "ducks in a row" do you commonly see overlooked?

It sounds like there is a lot going on with this. 

Roof and two ACs were 6 yrs old. foundation is sound and it's a brick house in a quiet neighborhood.

I am not qualified to make any type of foundation assessment but from what I’ve researched and seen in other properties, the structure seems pretty sound.

Sounds like it comes from a wily veteran too.

We are just speculating on the upward moving of this market because the house price keeps rising and there are organic factors that support it so in a moment we think negative cash flow can gradually be covered by picked up rising rental rate, but i guess its not financially sound on this deal

I normally only say yes to SFH's under certain conditions but you sounded like you have a few units which you need to lower any vacancy fear.Y ou could look at investing into commercial sized complexes where the value reflects the income instead of sales comps. 

@Eli M.The situation with your lender sounds a bit odd but I suppose different strokes for different lenders. 

Sound like a solid investment to you guys?

But nothing you described sounds like such a damage.
