@Tim Hunte Renting my the room is technically illegal in Philadelphia but its just as illegal as doing rehabs without pulling permits.

My property tax is very reasonable because I acquired it a while ago and in California, property taxes go up 2% a year max (unless you start adding rooms, ADUs, etc with permits and it's reassessed by the county).

Or 500 hrs as STR)Took a 40k hit when I sold my permitted Cape Coral  lot last year unbuilt.

When the sq ft numbers for pre-fab are quoted, they typically don’t include the costs associated with site work, foundations, and utilities; they are only quoting the costs of the ‘boxes’ that get dropped on site.Many jurisdictions still haven’t accepted pre-fab buildings as an approved construction type as well, which can lead to a longer and more difficult permitting process.I would do my due diligence for sure before going down the prefab route

Also pretty sure that the condo association would no permit it (and it's working great).Honeywell does have some updated models that will work, but I don't see any that are smart/Wi-Fi.

I will add that oftentimes the fixed costs with installing any kind of pool (fence, pump, permits, excavation etc) are so high that the marginal cost of a plunge pool vs something more standard is relatively small.

What is typically expected considering approvals/permits take notably longer to get in the Northeast.

Are you just looking for permit ready plans, custom design, and/or full services that include construction observation?

But I want to cash flow more somehow in thousands  not sure on your capital funding for Miami but if you have the capital and backing I'd look at development for STR towers in the 50-100 unit range. you can get lots around 1.2 million that you can go 12 stories on with structured parking in Wynwood right now that you can build a 15 million dollar asset worth 30 million. you can do the condo exit or hold it as apartments and permit short term rentals. there are some great articles about short term rental occupancy. miami has 22 renters for every 1 available apartment and has the #1 net migrations in the state of florida for cities and florida is the #1 net migration state. it is land locked and developer friendly. it's under built.
