Temporary worker housing situations etc seem like an ideal candidate for what I am searching for.I have looked into quotes for transport and even a 1500-2000 mile move might make sense given the prices of the lower end mobile home market in the Northwest & on most of the West coast.

That's hard to say nationally and I'm NOT an expert in the Baltimore market.I can relate though as I live in Denver but buy in Southern US.Going big allows you utilize, best in class, 3rd party management and there's no need to be geographically constrained.

Not saying you can do it while sitting on the couch, but one way is to buy stuff like this (listed on the MLS in this case):https://www.redfin.com/CA/San-Diego/3905-National-Ave-92113/home/147880176If you'd like to go through the exercise of penciling this out and posting, I'll share my POV on why a property like this makes sense.

Either someone who specializes in real estate asset protection nationally or a real estate focused attorney in the state where you are investing will be the best place to start.   

Long story short I find properties for myself and others investing close to public transportation to NYC.

Anyone have recommendations on what websites, etc you rely on for up to date metrics on market trends, both locally (I'm in OH) and nationally.

The price point is enticing but if you track the national internal migratory patterns of the US you will see that people are moving out of not into those cities.

When you are leasing, be knowledgeable about the area, the retail there, job growth, city growth anticipation, transportation provided nearby, it's closeness to highways, the school district, access, parking, parks and how well the surrounding area looks. 

Are you focused on lending to investors in certain markets or will you go any where nationally if the deal makes sense?
