Should look at population increase, job growth or future plans of infrastructure, transportation, redevelopment etc...

Your transport and installation costs are higher which offsets some of the benefit of the construction savings. 

There is no question in my mind that local zoning laws are a core cause of housing shortages but unregulated STRs are not helping.

Note in NJ, heating oil tanks below 2,000 gallons are unregulated though landowner can still be liable for cleanup.Sometimes closure in place is appropriate where excavation could undermine building.

Currently, I do not have a car, so I don't have consistent transportation.

A starting point would look something like the following.First outline the process.Identify marketcorelogic; Uhaul data; census data; Airbnb Data; Zillow data zestimate vs rent rate; Houses on market, consumptions rate, etcOutput: what market has potential inefficiencies or unforeseen growthIdentify neighborhoodsschool ratings; public transportation; crime spot data; HOA quality; proximity to major employer and average wages; opportunity zones; historic appreciation; historic average rental rates; etcOutput: what is currently working the area and what are BP members doing there as well as unforeseen growthIdentify strategies that are best for the given areasshort term; long term; BRRRR; arbitrage; etcOutput: which strategy is more efficient or applicable from user inputIdentify realtors/wholesale/etchighlight most active realtors/wholesale companiesOutput: connect with and understand local marketFunding typesbased off the price and type of units what is available and who offers the funding; BP member input on successful previous funding deals Contractscurrent trends in the area to close the deal from in the local marketManagementhighlight local management for long term or short term; contact info for Core four, inner and outer circle.

Considering the complexity of the structures themselves plus the added complexities of transport/assembly at remote locations, I thought the costs were extremely reasonable.

Buying new homes to replace them out of your pocket (estimate cost of new homes and transport, set up fees) or allowing people to bring their own (estimate vacancy while trying to bring in space renters)? 

I currently own two one beds, located in Carroll Gardens and Park Slope, I also own a 3 bed in South Slope that I live in.In regards to the four neighborhoods you mentioned and how they will potentially appreciate, I would say the following:PLG- I wouldn't buy a one bed unit here, as it primarily attracts families looking for relatively affordable singe family town houses, and doesn't offer much that young professionals would be attracted to.Prospect Heights- A great area full of dinning options, transportation, bars, etc. 

When I said no two "claimed" it by plunking themselves on the couch and the third ran home to get some transportation to haul it.
