As far as what I'm reading at the moment, I'm loving "The Compound Effect" and using "Flash Boys" as a switch up. 

This effectively prohibits checkbook IRAs.If such investments are held beyond December 31, 2023, then the entire IRA account will be deemed to have been distributed.See https://waysandmeans.house.gov..., then follow the link at the bottom of the page for specific language for each section above.Many SDIRA custodians are encouraging their clients to write to their representatives on this issue. 

In addition I have read books and talked to investors but I am still struggling to analyze deals effectively.

I'll keep my ears and eyes open for an aggressive/effective landlord attorney.

.- Using an attorney for a real estate transaction and mortgage structuring has been so easy and very cost effective.- Offering the seller more than they thought their home was worth made them willing to finance the home for 0%.Bottom Line - 1. 

Would this negatively effect the property in the long run with it being built in 1910?

This would effectively end the ability for accredited or sophisticated investors of using IRA funds to invest in private syndications.

I looked into them briefly for a unit that I was considering a traditional STR until next July and then 30+ day rental after that (when San Diego's STR quota goes into effect). 

While the current lifetime exemption is approx $ 11.7M, this is set to be cut in half effective 1/1/26, and that reduction may further be accelerated if tax legislation gets passed.
