Feel free to post more concrete details here or PM if you want. 

I have concrete goals but I live in a very very tough market.

Rent 1500 to 1600,  we are looking to rent it to section 8 tenant, The inspector will be there next week  my concern is because here there are no too many Frame houses (Frame houses are like houses in Maryland)  most of the properties on South Florida are build with CBS (Concrete block System ) Normally if the property were with CBS there will be no problem but on a Frame house i am not 100 sure

I then thought about GC'ing it myself, hiring out the excavation and then forms/concrete as most were NOT willing to do it separately here in Chicago.

One thing I want to negotiate in the deal is a small concrete building used for storage that is owned by an adjacent land owner that the current owner knows they are willing to sell.

The smell of cat urine, and more-so, spray is near impossible to remove once it is embedded in the subfloor ... it's even more tenacious than dog urine.We bought a property where tenants and their farm had been for 9-years ... it was a complete gut job - even the concrete slab, under the subfloor had to be treated to remove the smell.Good thing your tenant is paying over market rent as they longer the felines stay, the more it's going to cost to be rent-ready for the next tenant.

Achieving economies of scale may best be attained through volume, but learning how to do it on a small scale will pay generous dividends later; pitching the concept to investors will be much easier when you can show concrete results, and extrapolate from those results instead of being forced to rely solely on projections from a concept.

If you took pictures at your old GCs work, got several quotes from licensed companies, specified on that quote something like "remove non-compliant newly installed wiring" and have them done the work, then you probably have a bond claim up to $15,000, IF the GC is licensed and bonded -- which I don't see you mention.

., I've heard that the Garden City inspector is tough when it comes to concrete.  

Would it be best to put down laminate, remove and just have concrete slab, etc. ?
