@Bryan N.agreed - and my concern with granite is that it may stain if not properly sealed.

-Fix Roof-Renovate and re-arrange walls-Redo Electric panel and seal from moisture buildup-Remove tenant (found out she was section 8 but I got lucky and they already found a place!

While not a traditional flapper, the canister does have a seal on the bottom where it fits into the flushway between the cistern and bowl.  

Best course of action is sealing all gaps between attic and the floor below, then add insulation.

2) MLS3) Same agent from #2 4) Friend (also in Real Estate) passed it over, which is from wholesaler5) An agent who I met before, but then sealed a deal during a Happy Hour =)

Stay away from seller financed notes to consumers (homeowners) if there is not an RMLO license number and seal on the note and Deed of Trsut. 

It's a little more expensive than grout (plus sealant), but in the long run, the lack of needing to seal and reseal makes it more economical, supposedly.

It was only on the market for 3 days but the owner wanted to seal the deal right away & we worked it out.

It will seal the concrete and keep them looking good longer.  

Either way, there is likely little insulation in the existing envelope, but if the building is structural brick, it would be more difficult and costly to improve the insulation and air seal of the envelope (first hand experience here).
