For flipping a contractor is probably the most important, but it is hard to evaluate a contractor without a project for them to bid on, so a realtor is probably going to be your first call.

I can provide insight into the best practices for a smooth and efficient project. 

But my plan is to sell or refinance after 6 months to put my partner on title only as I need my mortgage room for another project.

In searching for land, I discovered that nearby new construction projects were purchased as "shovel ready, ready to issue."

I work 45 hours a week, so I don't have time for a 5 month rehab project. 

However, our experience has been that local jurisdictions frequently layer their own requirements atop of the national code - and have worked in places where the local code requirements required second doorways in dwelling units not protected by sprinkler systems (we are working on one such project now).Hence my suggestion to verify local code (for Baltimore in the OPs instance).

Just my 2 cents.Anyway, going to my Flip projects.

I recently purchased a duplex and bought the cheap China-made vinyl blinds from Lowe's (Project Source).

If I were you, I would look into leveraging that cash and maybe getting into a project or two for "fix&flips".

Your projected Vacancy reserves (7%) is too low.
