The water as you mentioned, but also the soil, any bugs or rodents, etc...If the guy only planted them and then you took over the the care and maintenance then it seems it is on you, unfortunately.I'd just build a fence and forget about this....

Summer time I went to long vacation out of state, came back and 3 days ago I went to inspect the property and found out a some of the doorframe cracks and soil around the foundation.

Big Hint: The area immediately surrounding the Union Pacific Railroad which has been labeled a cancer cluster due to contaminated soil is one I avoid.

Water hits a concrete second floor landing (outside 2nd floor entryway) and soaks into the old concrete and also runs underneath and then enters.

Hi Marcelle,How is your soil regarding a perk test.

Hopefully this is the case.My wife and I aren't carpet fans to begin with but we couldn't determine what to do with the stairs since they weren't nice wood underneath and wood treads that are stainable are a fortune to purchase.

Are there mini-split installers in your area that can work up high on your buildings top floors.What about heat and hot water, how will that be handled.Can the buildings existing plumbing and the line(s) to the main street waste line handle the bathrooms  and kitchen sinks (1952 lines might be cloggy and an endless source of complaint) have sewer scopes been done to see what they look like.Will you be required to put in fire escapes (as well as other modern fire equipment)--has that been budgeted for.Have you talked about tax abatments yet with the governing authority.Does the area show a shortage of apartments, or will it take a long time to fill units when they turn over.Hows the roof (and the real roof underneath--the wooden one), how many layers of roofing are on it, how many can be on it and still get financing.Does it have some unique history, ie. did Frank Sinatra always stay there, people think its haunted, once owned by the Beatles, etc..Who was the last Hotel Chain to Flag it and why did they shut it down (Legionaries Disease, poor economy, expensive structural issues, etc...)Just my 2 cents. 

They already did the dig test, soil log, and after that they told me that I need the survey to submit the plans to the township.

I have my legs underneath me (no more linguine legs) and the gloves are off.
