Your numbers show making about $100/door which seems to be what a lot of people aim for.  

Have you ever thought about a bar and grill, with a main room bar and a 2nd smoking lounge bar.You could call it "The Poker Room" and have a cards theme to it.Dark wood, low lights, lots of alcohol behind the bar, with bartenders in uniforms.A secret entrance in the back from the rear of the building, stars go right down to it.Pick a radio station aimed at a particular audience and advertise there to attract sames (birds of a feather).Bring in a live band (that matches the clientele) once a quarter and advertise that (all the bottled beer they can drink plus a kicker of cash for appearing).With ultra sanitary restrooms.Basically a speak easy type of bar.

Get off BP if that’s your aim.

Let's aim for after work around 6:30pm or so?

There will ALWAYS be charmers out there who spin a good yarn, aimed at emptying your pockets into theirs.

If that truly is her set of values, then your aim should not be trying to convince your wife of the financial merits of real estate because she probably already understands them. 

If we aim for a sale next spring, after 3/15/20, are we now paying long term capital gains on the project or is it one year from when the home is built?

Example if I purchased somewhere where unit price is $60k I need to purchase 10 units to get $600k of property but if I purchase somewhere where unit costs are $300k then I only need 2 properties   That is 1/5 as many tenants, kitchens, roofs, yards, foundations, walls, etc  I suspect you know the general benefits of house hack anywhere including experienced gained, supplemented residence costs, benefit of principle pay down,  ideally appreciation, etc.  

It works with hard money loans for purchase and rehab since you are trying to force equity in that scenario, but for long term you should aim for a deal that will cash flow with a fixed rate loan (or something creative like seller finance or subject to). 

That being said, I always aim to provide at least 60 days of notice (when only 30 days is required) as I can appreciate the time needed to secure new housing.My question for you all is, if the current seller provides the tenants with a notice to vacate upon the expiration of the sales contract's final contingency date, would I as the new owner be able to inherit their notice?
