We specialize in rent-to-own in the Baltimore & surrounding areas (including Glen Burnie). It certainly is an option for you. We'd be sure to find a home & seller who would be able to lock in a longer term than the typical 18 months. Depending on your short sale situation, you will likely need at least 2-3 years.
You are smart to do your due diligence. Although rent-to-own has been around forever, it is a specialized niche beyond the standard training of the average realty company. The professional you choose to work with should be able to tell you the difference between a Lease Option, a Lease Purchase and Seller Financing. These are 3 different types of transactions with different contracts and different ramifications, but they all have fallen under the general "rent-to-own" term. Even better is to find a professional who has had experience with all three.
Feel free to check out our website at http://www.BuyBaltimoreProperties.com. We have an FAQ section as well as video testimonials from both buyers and sellers.
All the best!
