My wife and I live for free already (just pay utilities).

Delinquent tenants aware of that so by not cooperating, not letting official lead paint tester to enter, they can easily fail the landlord to have rental license and that delinquent behavior now will work in their favor:With no rental license they block the landlord effort of eviction when they are not paying rent and utilities or not leave when lease ends.Also the gas bills will be fallen on the landlord instead tenants should pay their use with landlords have LCP (landlord cooperation program) protection with PGW.Does anyone have solution for this and who is willing to join the effort to fight the city that actually encourages that criminal behavior?

I should probably make a similar post asking for advice on how to better utilize the space.

That means half of your mortgage interest and half of any shared utilities.

Utilities in this area (-electric, water, sewer) are about $100 monthly if occupied. 

Also, with the increased living expense of your primary, you'd need more rentals just to sustain the cost of living increase. 

We will be moving out at some point and renting the entire property; each likely moving in our own directions with future investments, but both wanting to utilize the HELOC for these investments (e.g. down payment, renovation, etc).

For the other numbers like landscaping and utilities, you should use a general number.  

Like they say in professional (American) football, MOMENTUM is the key to sustaining a win.
