They could be the right sites, but it depends on what you are looking for specifically. 

I have searched high and low for services (Doorstead, Craigslist) but it seems no one is offering that level of service, or if they do I don't trust they can deliver considering my specific needs (experience with potential section 8 type community) in an increasingly gentrifying part of town.

I like searching for transactions and being able to quickly categorize them, even break down one specific line item to multiple categories.

Check on your STR regulations first to make sure it's legal to do so.You you already have the house furnished?

Specifically, I'm interested in exploring Fix & Flip as well as BRRRR strategies.

lol But yeah, there are so many opportunities in the real estate industry for unlimited growth, which is one of the main reasons I joined.

If we devolve into discussing the shortcomings of US presidents or specific politicians, probably time to close the thread. 

Is general industry standard to have 3-4 months PITI reserves in bank after closing?

I recommend being more specific, consider the number of comparable rentals, not just the total number of rentals.If your rental is $2000/month and you see rentals at $3000/month with long time on market, that is interesting but not as directly relevant to your situation.

If you have any more and/or specific questions, IM me.
