Definitely do your research there because if you violate Fair Housing laws that can get you into more hot water than perhaps anything else. 

Should be 12800 incomeOur expenses are approximately 10k a month on average-3300 for mortgage-900 for insurance -3500-4000 for utilities (water and sewer are provided by us) and we have on site laundry that costs us 1400 dollars included in those utilities. -1000 to the resident manager-500 to maintenance guy-600 taxesOur issue right now is that the previous landlords let the tenants slide on rent sometimes.

I use a scratch-N-dent place outside of Philadelphia, PA (private owner, small company) and after my last appliance purchase back in April 2018, he said the same thing.. all appliances went up about $25-100 depending on size (so a standard 30" frigidaire SS went from $1500 up to $1600 now), etc. 

Some condos the owner may be responsible for the furnace or hot water tank so you would just capex the remaining life.

Some ideas that come to mind: -Yeti style mug or Swell water bottle with your logo on it (filled with candy). 

Basically I just wondered if there is a standard formula — something similar to the MAO formula that rehabbers use.

Appreciate any advice

This is causing more wear and tear on what the house is made for, and the water bill im sure is going to be through the roof.

(water coming through ceiling) The owner says the tenant is required to do the maintenance.

"How you doing, your family member is selling me the roof over your head and you need to leave" doesn't seem like a good conversation starter.Lastly, is there an industry standard incentive that typically works to motivate "tenants" to move out sooner than later?
