All the best in your search!
In the spring there tend to be more listings on the market than in the summer and winter, so if you want a larger inventory to select from now is a good time.
I have added a link with some places currently on the market that are closer to a metro, but there are more places currently on the market in Chevy Chase and Bethesda, it really depends on what you are looking for.
Please feel free to contact me with any questions and I would be glad to be of assistance helping you find a place.
In addition, if you do not pay cash you need to consider that the mortgage interest might be higher and that could wipe out some of the gain you make by buying in a slower time.
The bottom line, I would buy an investment property when I see one that has good potential to rent, low expenses, and within my budget.
I am a landlord, former head of property management company and have years of experience with investment properties. If you are not presently working with an agent, feel free to contact me at 240 506 2370.
As for recommendations, I would try to find something with a low condo fee, but again, the property with the best rent:expense ratio is the one you want.
