[But, 3% Vacancy allowance is generally too low.

I have always been told you want to avoid s/c corps for holding real estate investments.FHA loans can be a great product to help you get into a property with low money down.

I reckon 3% vacancy allowance is far too low, and, perhaps $2,600/m is too optimistic?

The other 11 units are still  paying low rent (that's why I'm fully occupied).

But you should buy with cash.Mortgages in spain are low interest, but they give you only 70% LTV.

More importantly, it "legalizes" the pet and the pet owners feel better about that, and usually stay longer.Put a weight limit on dogs. 

A reminder to all investors out there actively looking at deals, 4th of July week/weekend is a really great time to make low offers on properties.

And those taxes look a bit low.

I have had a tenant in place for almost a year who looked like a bad renter on paper (low credit score, fluctuating income, criminal history, etc) but she turned out to be the dream tenant.

The only way this might be attractive is if you have the property (park/pads)...That said, it's a low-class market...how many people in your city are really looking for mobile homes?...
