I am well versed in laws pertaining to STR regulations, which are extensive in my market.

Given the timeline and the nature of these expenses, I'd appreciate any insights or advice from those familiar with tax regulations in such situations.Additionally, I'd like to know if I can claim depreciation, mortgage interest, homeowner's insurance, utilities, HOA dues, and other expenses associated with the rental units of my home from 09/08/2023 to 12/31/2023.

Or let me say HIGHLY regulated... and I would sit with folks.. and for the life of them they could not figure out how they got where they were...

The regulations and hoops you have to jump through often negate the monetary benefits.

After you give a kid an Uzi, are you going to show up and teach them how to use it, or just let the newbies fend for themselves in a dangerous and federally regulated area? 

Dodd Frank really helped big banks by, in the name of "helping consumers", added so many regulations on small banks and smaller lenders (basically big bank competition) that it hurt consumers.

They also need to have good exit strategy either wholesaling or flipping or rent it out for forever....they are very different than just buy in mls and flip it around strategy.I still remember there're three or four category of State tax deed regulation, is the OP knows about it ?

So no need to check into regulations or having the city or HOA change the rules on you.

They do require that a permit be acquired (super easy) and hotel tax get paid (a little more complex but there are ways to make it easy), but otherwise there are no regulations to speak of.  

Each with there own regulations above what the state and county requires.
