Hello BP, I've found myself in a rather fortunate predicament and could use some guidance from experienced investors.I'll be coming home from a 10-month military deployment with approximately 100k tax free income in the bank.I've been feverishly educating myself on all things real estate investing and I'm confident that it's the best investment vehicle suited for me.There are a lot of options on the table, so here are a few parameters:- VA Loan eligible, but...- NYC resident with NYC residency requirement for work- Focused on OOM investing (particular interest in Rust Belt for a variety of reasons: Pitt, Cleveland, Cincy etc.)- Student loans paid off.
