For example, the boom in transportation business, growth in jobs, and development. 

Infrastructure, distance to high-paying jobs, school ratings, shopping options, transportation, and location to lakes and the hill country.

We are located in Weehawken very close to the Lincoln tunnel near a transportation hub where about 15 bus lines converge before heading to port authority so I never wait more than 5 minutes for a bus.We have put in a lot of effort making the building beautiful by restoring details such as pocket doors, stained glass Windows and tin ceilings so my cap improvements have been more than a strict investor would spend but I see it as my home primarily with an investment as a side gig.

We typically have had good success with Alside here in Indy - custom windows are 12-16 weeks out right now all around due to manufacturing and transportation delays, so make sure you ask about lead times with your quotes if you haven't already. 

We also want to see strong and increasing population density, low crime, low unemployment rates, high median household incomes, and strong transportation characteristics (traffic counts, public transportation stops, etc.).

That makes much more sense.There are a lot of rules regarding ADU's including, but not limited to set backs (4' from rear and side), height restrictions (16'), size (max is 1200 but main house can not be smaller than ADU), parking (no covered or non covered parking is required to be added if you use the existing garage for your ADU so long as you are within range of public transport), renting (there are no longer requirements of owner occupancy of main house to rent out ADU (except for Junior ADU's), you CAN use tiny homes and prefabs as ADU's, if the detached garage is on the property line or inside the required 4' set back, you do NOT need to tear that down and if you do tear down the wall on or near the property line of the garage, you can rebuild it in its same location (prior years laws required you to then build outside the 4' set back), multi family properties are allowed 2 ADU's to be added plus you can convert non livable existing space into livable if you meet fire codes, and the list goes on.Another big benefit to the new laws is that if you keep the ADU at 750 sf or less, you avoid impact fees from the city keeping your permit costs down.There are a ton of other build out questions like costs of design/structural engineering, permit fees, etc.

Too many red flags.If we subsidize someone's "right" to own a home, why not subsidize their "right" to food, clothing, transportation, and everything else? 

It is ideally located close to a transportation hub where multiple bus lines converge making it a quick commute to midtown Manhattan.

This will cover transportation costs back to the US for anything major  plus other medical.Non life threatening issues in Second and Third world; setting broken leg $50; MRI scan $200; Hip replacement $15,000; Chinese Acupuncturist $10/hour; US trained doctor $50/hour just because he wanted to talk with someone from the US; Prescription drugs being over the counter from Pharmacist cheap, etc.
