It's like developing your muscles. 

@Jay Hinrichs but it my rentals are in a highly populated area. strong businesses, universities, hospitals, etc for the past 200 years. how worried should I be that I can't find renters?

There was a previous agreement that i inherited that stated they can use the lot until future development.

any good self development books out there?

Also using online income maps and the census website helps you analyze which area is best to rent in based on owner occupancy ratio, population growth, income, etc.Best of luck in your journey!

A good agent will help you develop a strategy, guide you when analyzing deals and has an established network of lenders, contractors and other professionals.

Here are some statistics to consider:Baltimore lost population last year as more than 5,300 people left the city, continuing a downward trend with a decline of about 6,000 people from 2015 to 2016.
