Not efficient! 

I tend to ask the same questions multiple times over a period of time to see if I get consistent answers.

When a rental is taken out of service for personal use the accumulated depreciation goes away over a short period of time. 

Even better, I might be able to snag it well under market value since it's an estate sale that's been sitting on the market for nearly 200 days.Here’s the challenge: while I could afford to purchase the property under market value, I’d be stretching my budget thin to cover the mortgage during the period I’d be remodeling the basement to make it rentable.

They provided registered address and limited mail forwarding for free and the process was fast and efficient.

If you want to quote out high efficiency boilers for six Tripple deckers for example requiring installation of separate gas, meters etc. etc. - that might be a situation where you would want to work with a contractor directly because you would have lots of different options with widely varying costs.

However what happens when the tenant vacates and now the unit has to be turned over/takes a few months to find a new tenant and during that same period of time the sewer line goes and you get hit with that $15,000 cap ex expense in addition to the vacancy and turn over costs.

So the incentives don't truly align so you have to REALLY want to make it happen and likely do several deals to create efficiencies.

There are quite a number of things that can make utilizing an FHA loan more difficult such as more barriers during appraisal, appearance of low qualification/little cash, typically longer closing period, likely higher interest rate, and PMI cannot be dropped without a refinance if 3.5% down.That said, just chain 5% down conventional loans, and make sure your duplexes pay for themselves.  

it depends, you going with an 80% efficiency system or 97%?
