I did work with New Western, I had great experience with them.

I know when it comes to many cities there are long permit processes and also there are specific air laws that go into each city.I would love to hear a story that goes over an experience pertaining to developing/rehabbing a property in the DC area. 

Given you and your investor both have experience in different areas, I’d say keep a flexible approach and compare city requirements before putting too much money down.

Nights, weekends, holidays, etc.To keep this on-topic, though...DO figure out what's healthy for you to manage but remember it's a process where every experience teaches you good and bad (and be patient with that process).DON'T sweat the small stuff (damage/costs under $50, undisclosed dogs, etc.) but DO find a way to learn, prevent, put in better practices to maintain your sanity. 

A renter for a stand alone rowhome is usually a different profile from a large apartment complex renter in my experience.

Does anyone have experience buying properties for cheap from land banks, renovating them, and renting them out/selling them?

Made a decent profit for my first experience Lessons learned?

But, you already know that having property management experience.

Also, if anyone has any experience in land purchasing I would appreciate any tips or websites on how to find the best deal or agent for the same.

I have some experience here, and my answer will be it depends.
