So far the high season is performing much better than the off season, but not as well as 2019, 2021, or 2022.  

And a little skepticism that the market would continue to grow at 5% or more on average (it's been ~7% average for the 8 years I've lived here)@Dave Foster I filled out the BP spreadsheet here for the sell or rent decision, and similar to you advice, selling and investing the profits in index funds performs only slightly below being a DIY landlord, making that seem an attractive option. 

Quote from @Joshua Wei: Can anyone recommend a company in or around Birmingham, Alabama that performs cost segregation studies for single-family homes?

They were all non performing - many renovation loans where little reno was done and maturity date already passed - guessing it was inexperienced borrowers learning how to flip and were getting "easy" money. ya they took me out of about 14 of my deals and well being that I was getting paid it was not my place to coach them they made loans far in excess of my positions. 

Say I have a first position performing note, what is a typical discount I should expect to give when selling?

@George Turner Alpine Building Performance is another great option!

Build to rent (BTR) is being performed by various developers in various markets.  

Great idea shooting for MTRs - we have one in Phoenix and it's performing really well.

Brands like DeWalt, Milwaukee, and Makita are highly rated for durability and performance, and they often have good discounts around Black Friday.

The best way to get a good contractor in my opinion will be to ask for bids on what they perform.
