I'm not HVAC specialist but from my understanding the chiller systems have shared water pipes but not necessarily shared duct work.

I sure don't want to be worrying about it in July, keeping me from water fun and bbq's 😎 

Up here, I am hearing from closing attorneys that no cities are performing water readings, smoke inspections, etc... and appraisers and home inspectors are not moving either...I can only imagine the Housing Authority...I would generally plan on at lease 1 months elapsed time with a Section 8 tenant under NORMAL conditions. 

, FAR (floor area ratio which is the max SF for the lot), lot occupancy (how much area can the building take up on the lot), green area ratio or pervious surfaces (a lot of places now require soft scale or where water can collect and not drain to the storm drain), parking requirement per unit (can the parking be offset if near public transportation), affordable housing, any view corridors to preserve, is it a historical neighborhood, minimum size per unit, and any public enhancements required?

Room renters would have Water/Sewer/Garbage and electricity included4.)

Not sure how you're going to get those loan terms (no DP, low rate, PMI) otherwise.For the most part your analysis of expenses looks good:I think closing costs will be a little higher.Typically, the tenant pays the water/sewer in a SFR.If this is a house hack, you may want to add in the other utilities and lawn care.

Do a routine inspection, check the plumbing under the sinks, check the drains for free flow, check for running toilets, check the base of the toilet for leaking flange seal, dripping faucets, change the furnace filter, inspect the attic for potential roof leaks, check the condensate pan under the HVAC, check the pan under the water heater.Common sources of smells are pets (especially cats), kids peeing somewhere other than the toilet, garbage/refuse not being properly disposed of, plumbing issues.

My capex budget includes roof 25 year life span, floors 10 year life span, appliances and hot water heater 12 year, hvac 20 year life span, bath and kitchen remodel 20 year life span, etc.

First of all, typical rent rolls are eaten away by 50%-90% in expenses, mortgage, taxes, water etc.

I'm not sure if on the Property management or asset management side there is any thing about delaying paying building bills, water, electric, mortgage, insurance....Kindly let me know if any of you aware of any laws or programs that we can apply for to protect the business until this issue get back under control.
