Your household names: Ernst and Young, Deloitte, KPMG, etc all offer audit services, as do your regionals like Grant Thornton.A full audit will typically consist of spot checking everything from invoices/receipts tying out to specific checks paid by accounts payable, and down to leases being input into the system, and tying rent payments to cleared checks.  

You could have a zip code with 1000 household/house ; highest price PSF for that home lets say $1K/sqft ; $1,000,000  but 89% in that neighborhood works for USPS.

The options are either the tenant pays for the damage of any of their household occupants, human or animal, or they get evicted.

There are two classifications as alluded earlier one is the property itself (used by appraisers) and one on the neighborhood.Mostly people here refer to the neighborhood.I’ve always looked at medium household income to hedge the neighborhood.

If I use my FHA loan, after a year of living in the household, can I convert my FHA to my LLC and still reap the benefits of that 3.5% down payment? 

The median household income in that zip code is $60KThat house will never rent for more than 3K on a good day.Sometimes its better to look away from estimators and look at what is actually happening.Sorry to burst your bubble, could still be a good deal.

I ALWAYS require MINIMUM 3X rents in gross household income, no exceptions other than pre-paid for FULL lease term (yes, I lease this way, not theory).

I reviewed other market conditions (population growth, median household income, etc.) and I ended up passing up on this deal since it didn't have a population growth over the past 2 years. 

The appreciation and B+/A- area being under nat'l median household price is a win.
