I have some colleagues who, as they call it, have "investment properties" near the King and Prince and Sea Island, but I don't know their numbers.

My name is Prince Martinez and I am a new member to BiggerPockets.

So, for example, I've found in the Montgomery County and Prince George's County MD suburbs of Washington DC, the houses below $250,000 will cash flow about $500 per month after PITI + HOA or condo fees, and the profit margins drop off significantly above $250,000. 

Quantico is located in Prince William County but it's right on the border of Stafford County. 

You are going to have to kiss some frogs in order to find your prince.

That being said, I think it'd be easier to cashflow in Prince William County but the further out you get from the city the less insulated it becomes.

There is no way I would advance any developer 70% of the purchase prince unless I get in exchange from the developer a bank guarantee for all the money advanced, which I can execute right away if the deadlines for construction, for signing the deed etc are not met. 

@Ali TayehFind the house people want to live in drive a mile away from the house and start working back towards your starting point.Adjust your cost/rent expectations accordingly.kiss enough frogs you might find a prince.

In the meantime, I am exploring the possibility of doing STR or renting to travel nurses, or other strategies.I would love to get some advice from people doing STRs in Prince George's County MD or the other options I mentioned.

Just keep plugging away, gotta kiss a lot of toads before you find your prince.
