Should I put concrete around this area prevent water from seeping into the foundation and basement windows or pitching the ground level so water drains out faster towards a drain that goes out to street drain. 3. 

Sounds like you already know what you need to do, both businesses won't work at its optimal level at the same time, and I'm a big believer in committing to something, even though I'm sort of struggling with that myself lol  

That’s an important ruling, because whether or not rentals are a business largely depends on the level of activity involved.

I feel like in a market of $1800 apartments and $350k 'entry level' houses, there would be a huge demand for $1200-1400 rentals and sub-200k new homes, even if minimal in sqft and design.

It's their fault, and the power lies with them to reverse their poor past choices and pick themselves up a bit by their own bootstraps.You're going to tell these new tenants that what's primarily wrong with them is not a legacy of a crime against humanity in the form of three hundred years of black slavery, followed by an unfunded emancipation that turned a huge number of Americans into desperate economic refugees based on the color of their skin, followed by a legacy of organized race hatred, bigotry, pseudoscientific and religious condemnation, and of course overwhelming and widespread intimidation and coercion, followed by a series of failed half-hearted half-measures coupled with an absolute refusal to consider slave reparations and the most lopsided minority levels of poverty and incarceration in the developed world.You're going to explain to these black folks that all that is of secondary importance, and what's REALLY important now is that they get better managing their money so they can hand it over to you more efficiently and you won't have to work so hard to get it.

It's just a lot easier to do your due diligence if the property is close by, and you can react faster to anything that has to be taken care of.

SFR from my perspective works best in a lot of post industrial towns - Chicago, Cleveland, Philadelphia, Baltimore - where rowhomes proliferated lending the stock an even greater level of standardization than most apartment building have internally along with a very low cost/unit and an outsized ARV on a refinance.

Make mistakes faster so you can get to the success.
