For instance, there is an old 8-unit complex on 9th & Willow where the city/caltrans plans to put in a sidewalk.  

You're probably better off pounding the sidewalk and knocking on doors.

(Engineering, infrastructure such as utilities, roads, sidewalks, etc.)What will the construction costs be?

Then, the city cited us for some apron and sidewalk violations and that cost us another $4500.00.  

But I think your hourly rate may be such that the opportunity costs for you to be showing units, handling tenant issues, and shoveling sidewalks would be too high (and this from a die hard self managing fan).That is, you may want to focus on what you do best and most profitably: dentistry.

You should first talk to the zoning department to find out if you can do that, some municipalaties have requirement of only s certain a percent of the lot be "impervious" (which means rain water can't go through the surface, so building sqft + sidewalk + pavement).

And you're lucky they didn't cause a sidewalk to be covered in a sheet of ice when that hose was used.The use of the exterior faucet AKA hose bibb when temperatures are freezing is something to be prohibited in the lease, so be sure to add this somehow.

With two days after the snow majority of properties have had there sidewalks and stairs clean.

everyone said quitting their full time job. i work for the city and the biggest benefit of the health insurance is only a few dollars per month for my family. i went to those health insurance truck that parked on the sidewalk to get a quote. i am married with only one 2 year old and planning to have another one. they told me with my salary. it could cost me about $500 per person/month in my household. let just say without the 2nd kid. it will cost me about $1500 per month for 3 of us. that's without going to the hospital or anything happen. i want to quit my job too but my health insurance will be from a few dollars for my family per month to $1500 per month. what's your opinion?

It may or may not work for them.You might tell them something in terms of your own understanding, but their understanding may be quite different.There's a reason why you can walk past billionaires on the sidewalk all day long: they choose to remain anonymous.
