Sandy, I am not sure I agree that you have to wait to do the 2013 budget, but that is neither here nor there. I would suggest adding a category with a 3/5-year plan for repairing all the plumbing issues. If you have such major issues now that you have to repair 4-6 major line breaks I would do a complete needs assessment.
If the Owners are wanting to get rid of the PART TIME on site maintenance tech, then you have bigger problems than the plumbing issues. It is NOT less expensive to have to call professional plumbers and other service techs since they charge drive fees, service call fees and the additional per hour charges. They might be able to contract with a Maintenance Company (a lot of property managers use these in Chicago) but I doubt they would be less expensive overall, plus it is a less effective tool for resident retention since residents may have to wait longer to have their work orders attended to, as well.
I wonder why your Owners are not seeking other investors who could partner with them to add money to the pot for some of the repairs? I wonder if they would consider refinancing the property and putting some money back into the property? I also wonder if they do not have any replacement reserves budgeted for any of the capital improvements? I doubt they could refi with a HUD loan since they have extensive problems, but maybe a different loan source could be found. To me, and I am a simple person, if the Owners are willing to sacrafic the loyal Maintenance Tech thinking they can save a few bucks, then there is something else wrong that is bigger than the both of us. In addition, if the Owners don't want to plan for the future in terms if getting money to install the gutter extensions, new windows, shore up the plumbing, and set aside something for new HVACs, then they are THOSE kind of Owners that take, take, take and give nothing in return. With funds to make some necessary improvements, they could at least position the asset for a sale.
