I have no town houses and do not know if all your external is covered but I can tell you that my spreadsheet places cap expense on a kitchen at about the $45/month you are estimating total.I am not trying to be discouraging because I think it is great that you have started and that often that is the biggest hurdle.Good luck@Laura C.

But I have accepted deals with their initial counter because it gave me a spread.For example, the bank stated they would do an internal BPO if I countered, and to be honest I thought the internal BPO would come in higher than the external.
