@Brady Bitter First what are you calling "securities"? 

Comparing rates and terms across lenders can also help you secure the best deal.

As I’m nearing retirement, I just invested a similar amount in first trust deeds secured by real estate at 9.75%.

Talk with some securities attorneys, brokers, lenders. 

For example I have an account for each property and a sub-account just for the security deposits for those properties.

With $200K-$250K, you can secure high-quality rental properties in both cities while benefiting from steady appreciation, strong rental demand, and landlord-friendly laws.Oklahoma City has a rapidly growing economy, with major industries like aerospace, energy, healthcare, and tech fueling job growth.

Over the last year, I've developed a passion for real estate and want to be able to use it to generate income and secure financial freedom in the long run.

Not likely.Maybe some of the tenant acquired their own washers and are using them for cleaning but your dryer for drying.Get a security camera and mount it in the area and post signs saying the same.

Safeguard reached out to me when I was in my mid 60s, and offered lending notes secured by real estate. 

That is what the security deposit is for and if need be, the small claims court system.
