If your girlfriend is a mature and intelligent individual, money and the rules of engagement should not be a banned topic of discussion.Adults talk and discuss money.  

that garage is an eye sore. need to tone that down. do this:add shutters to the front window, match that color with the garage and front door paint. it needs one mature plant, ideally, something with color (blue evergreen garden variety (dwarf size). nice buy. ideally, garage door could be made to look like a wood stain, and shutters match.

Less to worry about if the dog is mature and the tenant has good references from previous landlord(S).

D is more mature and seems to be handling speaking to the other tenants when their is a problem just fine, sometimes coming to me for clarification on the rules or advice.  

Location is San Jose, CA.After all of your excellent advices, I rented the house to a mature couple who were both still working, and it has been a heavenly experience!! 

All four units are identical, and according to my research should rent for between $725-750 per month.

Because of the affordability/utility factor, for units that are otherwise identical, SEC 8 will pay the most rent in an apartment with shared walls and the least rent in a single family home with all walls exposed.

My basic understanding is that you charge the tenants each month based on the ratio of their unit's square footage to the total square footage of the property.I would give credit to the BP member who I saw this from but I can't remember.For an easy example, consider a tirplex with identically sized units.

This is identical to a HELOC.

My personal cash flow will be increasing in the next couple of months, and I think I may be able to refinance to a slight positive cash flow.Additionally, the tenant emailed me that he wanted to add a pet (went from one mature dog to two puppies).
