Structural Issues in Brick Rowhouse - Idea of Repair Costs

[Will Johnston]

So, fairly new investor here.  I see a lot of end unit brick rowhouses on sloped lots that have some kind of structural issues.  Some minor stair-step cracking in the mortar, some slight sloping in the floors and out of square doorframes, a bit of bowing in the exterior wall.

I'm pretty good at finding these issues, but I have no idea what it costs to repair.  I could be looking at $5k or $50k.  Does anyone have any experience with this sort of thing that could give me some kind of ballpark?

For reference, here's a place I'm currently looking at.  Not the best picture, but might hopefully give you an idea of what I'm talking about.  It's not so bad that you look at it and cringe at first glance, just enough that I'd definitely want to make sure to stop it from getting worse and fix what's there (if necessary).
