New floor structure, new layout, new HVAC, updated electricity, new roof, new window package, new water heater… pretty much the works.

IMHO, the housing authority is trying to bully you.I would lay out my argument to them, with comps, and be willing to tell them to pound sand if they can’t agree to a reasonable way to get you up to market rents.

Could anyone layout the key factors in studying a market?

We've been using the following system/software and it's been extremely helpful. http://www.transported.co/321-timber-glenn-way-ind...This allows us to virtual walk through's of our properties so residents can understand the feel and layout better than pictures could ever tell them.

So Google “real estate meet ups Baltimore” , pick several and go network.In addition to defining your strategy/focus as Ned mentions above,  another action step is to lay out the steps you need to complete (preferably in priority order) to set yourself up for a faster ramp up in your area of focus.

I am from Europe (Denmark) and I want to use all the content and education available here on BiggerPockets to begin my real estate business here in Denmark.There are different laws, different markets, niches I could imagine.I'd therefore like to ask if any of you can lay out what are the most important differences that I should notice.

A thorough review of the HOA covenants should help you make the decision as that will lay out duties and responsibilities and the homeowners' potential risks.

The kitchen layout of this small property looks a little strange to me.
