I feel like it's a great niche to target and specialize in, but the challenge will be finding the buyers.Other than the one-time buyer, how should I go about finding other investors that are 55+ that would be interested in this specific niche?

You can even find specific articles regarding Logan Square.    

I want to know if there is a course or specific book anyone would recommend for me to take or read.

Do you have a specific property that fits this mold? 

Is it amount specific?  

I can't give any specific names on BP, so yeah..The criteria is unique, it's all based on your end buyer being lined up and ready to close, so I'd suggest building a buyers list first, or get in contact with agents who work with cash buyers. 

It sounds like it use to be a little clunky back in the day, but has improved - but couldn't find any recent discussions on BP about Rent Monitor specifically.  

Specifically  flipping houses, and buy and hold in the Georgia market.

A cash flow analysis determines whether I buy a specific property.  

I am interested in learning more about Buy & Hold rental property investing, especially in specific areas of Ventura County, California and Cleveland/Lakewood, Ohio.
