If your looking to invest in homes for rentals less than 150k range, Prince George's County would be a place for you to start. You can definetly find detached homes within the price range less than $100K. Some of those turn key and some that need some work. I work with a few investors that purchase rental investment properties and make a good return on there investment. You can get rents up to $1,800 in certain areas.

The investment condo market is a viable option, just be aware the monthly condo fee's can vary widely which can reduce your monthly rate of return. FYI property management fee's average 8%.

North Silver Spring, including Leisure World, is a great option. For example, I just sold a unit in Leisure World with a tenant already in place for $95,000. The Condo fee, taxes & insurance came out to $770/month and the rental income was $1,500/month. with around $700 clear you have room for property management and a mortgage if you needed either.
There are also some townhouses and condos in the area that present similar opportunities.
