I came across a property in the identical situation and am in the process of negotiating with the bank.

In Washington state we sometimes transfer in or out of an LLC and simply write "mere change of Identity" on the tax form.

Not sure about the HELOC, I am currently in the same position as you with my first property being a duplex with almost identical numbers.

My broker created this pretty cool tool that identities properties that are undervalued in the market.

Having that many units would be very difficult to get any majority of them rented out via VRBO since you would likely have ~20 identical listings which wouldn't help sell your vacationers on staying with youINSTEAD: I rent out a studio apartment in my primary residence on AirBnB and have had enormous success.

His whole identity was probably tied to his army persona and that is now gone. 

In a market where median and average sale price are identical, # of Units * Median Sale Price = Volume.

For what it's worth I plan to build an identical duplex on the adjoining lot but it will probably be 6-8 months until I start on that one. 

The best possible comp is the identical floor plan right next door.

Well...https://clintcoons.wordpress.com/2013/10/16/seller...This link goes to an article that describes the situation I originally proposed almost identically...BUT it still doesn't clear up the WHY this regulation exists for builders.I have read multiple articles now...and done multiple searches...and this is what I have found:In Dodd-Frank....the builder - "involved with construction of" - seems to have originally had the intent of deterring timeshare developers who were acting as seller/financers and using deceptive practices to lure would be owners not contracts that they knew would never...or eventually not...perform.The 1 unit rule and 3 unit rule seem to be in there as a go around for builders willing to develop other entities etc and then seller finance that way...so confusing...and so little written or discussed...on my topic anyway...that I can find.
