Always think about the challenges the next developer will face. 1. fault line reduces the buildable area of the lot = reduce property value2. talk to a structural engineer & contractor about the added design and costs associated with both the fault line and the retaining wall. 3. if the steep grade is too steep then you might need to pile drive a wall vs grading and building a retaining wall which adds a lot of cost. 

It can use new windows and kitchen cabinets (the current ones are still functioning fine) but aesthetically and for value purposes, could benefit from a rehab.

Zoning for RM-1Any building with an RM designation can be used as a residence: for one family or as a multi-unit building.

Aesthetically and from a maintenance standpoint, I would prefer one of the vinyl options over carpet, but I just had to deal with noise complaints that had carpet in the upstairs unit already, so I am nervous to spend the money and install either vinyl option and the sound is even louder than with the carpet. 

I've heard you can designate a family member as an employee and avoid taxes if you keep their income under a certain limit.

You cant, do you have this super-duper never before seen design lol? 

In addition, rental property owners who live outside Maryland must designate a Legal Agent who lives in Maryland to accept legal documents.Now, this does not have to be a property manager, it can be a neighbor, friend, relative, etc.  

I'm developing a software designed to simplify the networking process for real estate investors.

But from a design perspective it looks much better and if you get more bookings from that fact alone, dressers are worth it! 

This cost variability depends on factors such as system design, property size, soil type, and system capacity requirements.
