If a flip, I agree with the comment above in regards to the top coat.

I suspect the walls have had 15+ coats of non-leaded paint since 1978, but I don't know how deep the test goes.Are there any situations where lead can cost a modest amount of money to remediate, or are we facing a huge financial burden once any lead is found?

I don't want to sugar coat anything.

It's one way but I prefer to "hack the system" and use the data from really great organizations who have spent crazy $ and human resources to peg the hot markets of tomorrow, and just ride there coat tail too profits. 

Many contractors will lay bare wood, stain then coat to you choice.

hahaha  It all depends on what is there, and to see it first hand but, it may be savable... clean, prep, apply a coating system to it.. taaa-daaaa, you now have 10+ more years on it!

The people with a 20 year old kitchen probably won't expect the same $ as their neighbor with the shiny new kitchen, fresh coat of paint and new landscaping.Two targets might be Seniors with Long-time Ownership and Owners with Low Financial Stability Scores (FSS).

@Kendrique Coats I'll give you two mistakes that I personally made early on:1) I didn't know how to properly screen tenants2) I didn't know how to properly manage a rentalSo long thousands of dollars and 2 years of misery!

@Kendrique Coats - I know one great person in the Illinois area you should connect with @Fernando Angelucci.  

But one fair housing complaint, botched contractor job, or prolonged eviction can quickly cost you far more that a property manager, so don't sugar coat it: Go in with your eyes wide open.
