Based on the numbers, I was very conservative allotting for 10% each month for vacancies, repairs, capex and property management.My question to you is, based on the below numbers and information, do you think it is a solid investment?

Is this common in all programs and if not, is there a program that is regarded as one of the better on-line programs out there allowing me to finish the study process in the allotted time that I have been given?

I know allot of people that do this and as a landlord, if I knew up front that was there intent, I would rent them on a month to month and increase deposit and rent for the potential headache.

Lessons:  1) Don't like the answer, go elsewhere multiple times, 2) no mega banks, 3) work with a friend to fix small stuff that comes up, 4) VA loans can be used on more than one home so long as don't exceed the cap ($453K) however, VA funding fee is more each time and there are other rules to follow with intent and occupancy you need to be informed of  5) some mngt companies are passive in repairs, checkups and finding tenants (due diligence and ensure they meet your criteria instead of you meeting theirs 6) rental and appreciation markets vary drastically from place to place...your #s and analysis must adapt to the area, 7)  around a bustling base or post...use creative marketing to attract your target audience because you speak the language to a large portion of the people coming and going.  8) If you use mngt company...help them succeedThere are allot of scam artist companies that capitalize on the dependency of a relocating Mil families...while giving poor service with a smile just to sell something. 

I will be using my VA loan (very attractive terms) but the total loan amount goes over the VA zero down allotment.  

I know here if I don't provide a proper notice of claim against or deliver my deposit settlement within the allotted time (14-21 days), I forfeit the right to withhold any of it, no matter how possession was returned. 

There indeed were no similar comps and so the appraisal was based on nearby duplexes and triplexes with only about a $10k increase allotted for each additional door/unit above the comp properties.

going in with your highest and best offer from the start and then standing firm there is allot better strategy in this market rather than submitting low ball offers hoping to negotiate them down.  

Waldorf Maryland has an "easy" commute to DC and also offers allot of investment opportunities 

Allot of great information from professions everywhere but one thing that I always see is service exchange.
