I have zero hesitation about buying another.

What is your risk tolerance like?

You get zero collateral in the equities markets.Either way you invest, just be sure that you have 'risk management' rules set up to protect yourself. 

Specific to you as a real estate agent, track all miles you drive showing homes and write that off in Sch C P2 box 44A (yes I have that memorized) to the greatest extent your CPA tells you it's lawful to do -- this is one of those magic write-offs that minimizes your tax burden while having zero impact on mortgage qualifying income.

His point is clear though, if you have the risk tolerance, you can be financially free long before you can be debt free if you employ intelligent leverage.

It sounds like the situation you’re describing is essentially zero interest loan. 

Rentometer, Craigslist, Trulia, Zillow, etc. have zero rental information for my market.

Scenario: 2 properties, 100% equity, but ZERO Cashflow!!

Besides the rent and the costs normally associated with move out (cleaning, paint, etc.) the tenants are also responsible for marketing costs (which are basically zero as I do all the work myself and do not pay to advertise) and commissions that have already been paid, but these again are usually very minimal fees that are not really making any of my tenants think twice about leaving early.
