Especially in large metro areas, neighborhoods can change dramatically on a block by block basis so you really need to understand the lay of the land.

Their response...I rather pour concrete down the drain than sell to you.

I have also considered having the concrete polished but there are a few spots that have patches and/or  leveler and I am not sure how well it would come out?

My thought is a large concrete wall higher than it and the flume as well as additional fence, soil, tree boundary.

It's bizarre to me the lack of concrete, proactive planning.

For rental comps, I do a market re-search of whats available around a few blocks comparing other proper/ amenities.

I do but BP blocks it so I just copy paste it here.

R-value on a slab depends on a lot of things, with the biggest variables being thickness and density of the concrete.

Not figuring this out can wipe you out.4) Ring Cities are best in Suburban Detroit - PM us for definition or search for our company blog posts here that cover this.5) If you go into City of Detroit, you really have to check each block-by-block.

I've seen extensive foundation repairs done to cinder block walls that are bowing from external hydraulic pressure, and they've been repaired with extensive steel beams, tension systems and a drain cut in for around $12,000.4" is a fair bit of slope and to put in floor leveler...well, that's a lot of floor leveler.
