Assistance with estimating basement repair costs

[Bruce Steinetz]

I am looking for assistance in estimating repair costs for basements when sizing up  potential rental properties. I have two categories of basements in mind.

Category 1: the basement shows some hairline cracks at the frost line; and some stair step cracks but no heaving, and only minor evidence of moisture..

Question: what type of repairs should I plan for? Is there a simple rule of thumb for cost per linear foot of basement wall to help me make the estimate?

Category 2: there is clear evidence of water seeping in at the foundation level. And some cracking of the walls, but no heaving.

Question: what type of repairs should I plan for? Is there a simple rule of thumb for cost per linear foot of basement wall to help me make the estimate?

Thank you for your help
