So this is not just drilling some new 2" Tapcon screws into the concrete blocks, last one I had done they had to remove everything to the concrete blocks themselves, then epoxy in metal fins etc...all I am saying it's involved. 

The homes have a new, 3 step simple concrete porch with no hand rails.  

It also saves labor on sanding when you are installing new drywall and can be sprayed over concrete.  

Concrete is low maint.Frank

Unless you're talking about foot thick concrete, it will sound like  a herd of elephants upstairs.What I would do is ask the downstairs unit if they would stay if you got rid of the upstairs problem. 

Tanks were concrete and appeared to be in good shape.

This gives me pause but I couldn't think of anything else to say/question so I went ahead and scheduled the viewing.Now, I don't have anything concrete and the application will give me more to work off of but I'm getting a gut feeling that this won't be the best set of tenants. 

Ultimately, I was able to leverage these skills (with a little more polishing) into a career as a Product Designer in the tech industry.Despite all of these varying pursuits, I never forgot about Rich Dad, Poor Dad, or the idea of real estate investing.Fast forward to today, I am working and growing in a rewarding career that I really enjoy and am excited to start getting my hands dirty.

You need to wait until there is a concrete lease violation that is presentable to a Judge.

You'll also want a shop vac, broom and dustpan, rags, mop, cleaning supplies, left-handed smoke shifter, concrete elephant, etc.
