@Zach Howard the basics of the Rental Purchase Calculator is easy to understand and replicate.Google and you can find many similar spreadsheets for free.

I doubt you'll find a MF that you can get into for 40-45k that will give a similar return that isn't in a terrible neighborhood.

My question is, If one is to be strictly commission based, Is finding a broker with mortgage industry similar to finding a broker with real estate?

It's like drafting a rookie QB and expecting to win the Super Bowl his rookie year.Based on the tax increase, my assumption is you chose a great appreciating neighborhood and have a similar mentality to me. 

I'm in a similar situation.

Quote from @Paul Gupta: Hi, in California, For jobs requiring a license, there was CSLB (contractor state licensing board) which would give either a General Contractor license, or specialty licenses by trade (~60 specialties such as concrete, welding tile, ) https://www.cslb.ca.gov/about_us/library/licensing_classific...My Q: does Maryland and DC area have similar requirements? 

Similar to point 1 but also could be standalone. 5.

So, I also require that :Monthly Rent + Monthly Debt Payments <= Gross MONTHLY Rent * 45%This is similar to how mortgage qualifications work by considering the applicants' debt loan along with their housing cost in relation to their income.

I have used a similar program in Appfolio. 

Originally posted by @Mark Whittlesey: I would get a UPS Store (or similar) box instead of a PO Box.It costs more but is much more flexible (is an actual physical address, can receive UPS and FedEx etc.)I had a PO Box for a while and got rid of it for exactly those reasons.
