Now is one of the best times to get into the market, once the Fed starts lowering rates that's going to bring more demand into the marketplace causing prices to increase at a faster pace again so if you get in now you capture that growth and get the opportunity to refi when rates are more favorable in a year or two.

The process was straightforward, rates and terms were flexible, and I completed my home renovations without any issues

Landlord might not want to remove them, and would be keen on keeping them, but at a new rate/terms. 

I buy my leads from a friend offshore with a 80-90% contact rate.

I was just informed from my mortgage company that in their eyes a point = .125 so if my rate is currently 6.375 buying 1pt would drop it to 6.250.  

Are there any resources where you can put your income, purchase price, down payment and credit score and see potential rates and which lenders do it?

@Cillian KellyI never do because my rate is 3%.

Also insurance rates are cheaper in SC than FL.

The property I've set my sights on is a 9-plex where the owners are willing to carry 70% of the loan at a 5.5% rate for a $1,800,000 building.

How you proceed will depend on a few factors:- financing will depend on your exit strategy - you'll be best off if you can decided the exit plan (LTR, MTR, or STR) before buying- Since you're not employed and living on savings, what is your burn rate and your cash runway?
