If you don't have any other investment you want to embark on with your excess fund that would be generating some sought of income for you on the side, I am sure your best bet is to go for 20% downpayment on your real estate purchase because it helps you build equity really fast and if due diligence is properly followed in the purchase strategy then you can be rest assured of stable and steady cashflow. 

Sounds you like you really hit the ground running and have some clear goals for progressing further -so you're way ahead of a lot of new investors. 

Im willing to bet you have a pretty good interest rate on that loan too. 

Based on the numbers you presented, this is not going to be a cash-flowing property and is solely a bet on appreciation.

This seems to make more sense in a college type setting but another opportunity to increase cash flow from a SFR situation.Keep sharing your progress.

It is better to fail (forward) towards progress, than drop off a cliff (by taking out a second and doing a really big, bad first deal).I see you are in Maryland. 

I'll keep the community posted on my progress and I'm sure i will have tons of questions so, please bare with me. 

Start with MHC's that are in the "PATH of PROGRESS".

Perhaps the Cap rate is higher in your area.With regards to financing, I wouldn't bet on seller financing.

Your best bet is marketing.
