Thanks @Jeff Chisum , can you expand on this? 

Gaining knowledge from seasoned investors and expanding your network might lead to insightful possibilities.A reasonable starting point is to have $25k in cash, but keep in mind that there may be other charges to consider, such closing fees, property management, and unforeseen maintenance.

We were very successful with these rentals and decided to expand in 2017.How did you find this deal and how did you negotiate it?

Remember this is the worst they will ever be, these things are getting rapidly better.

Could anyone provide recommendations on the most effective strategy for expanding my real estate portfolio?

The past twelve months I have been intimately involved with expanding offerings and niche programs with my current lending partner (based in NY but still with ties to South Florida.) 

Can I get your thoughts on whether I should expand my cabin near Gatlinburg? 

You may want to consider working with your accountant remotely to expand your options.I would also recommend looking for a tax strategist who is willing to work with you throughout the year, not just when preparing your tax return.
