Things like "roof failed - past useful life expectancy should replace".

If there, I put that I'm not responsible to replace/fix if it breaks (since not typical to provide these)3)YES!

I furnish kitchen sink and bathroom hair strainers, cheaper than having a plumber come in to rodding the lines.Check and replace strainers as needed

Depreciating has reduced much of the income and probably just as big, I have put a lot of money back into my buildings to improve cosmetics and efficiency while modernizing them somewhat.

I bought it for $330K and will put $90K worth or rehab on hard money as well ($95K now since a furnace needs to be replaced...

: less chance of repairs in the first few years, less chance of buying something with hidden repairs, modern= more attractive to tenants.

With the surrounds, I've had one that was installed new and after a couple of years, it had to be reattached....the original one was replaced because it was coming off as well.I think look at the total cost including install, buy a quality one that will last (not the cheapest and not the most expensive) and have it installed properly. 

Tenants in place, can keep or replace, pretty turnkey. 

Also, depending how you construct the replacement building you could greatly lower the cost of the flood insurance (elevation of lowest floor vs flood elevation,...).  

It doesn't mean you shouldn't buy a property with galvanized pipes, but understand that they may need to be replaced at some point and the cost implications involved.
