I would be asleep in my bed until 8am, at which time I would tape a large 8.5" x 14" piece of yellow paper to his door with the word "TRESPASSING NOTICE" in big bold letters at the top and the details of breach and criminal trespass below. 

Thank you Great Tip @Pearly Tan ..

. - By this point wifey is in the tail end of her 3rd trimester, obviously no one is moving anywhere at this point except onto a hospital bed once in labor.- They rent out House A to cover the mortgage, 12 month lease. - Wife has baby, apartment too small, no fault evictions in Oakland are a pain in the butt.- They purchased another home with an owner occupant loan and 5% down a few months after closing on their first, about a half mile away (job transfer to other side of the country = that exception is granted on a routine basis, it being the exact same neighborhood makes this unusual).- Underwriter would have been within reason to ask for a birth certificate to line the date of that up with the rest, but in this case elected not to.Note the unusual circumstances surrounding this.

@Andrew MonaghanYou may want to consider the outlying areas such as Apache Junction, San Tan, Casa Grande, Coolidge, etc.

@Tony Tan It is abandoned personal property.

Also, I think they are mostly 1 bed, 1 bath but it doesnt say that.  

On the conservative side I'm looking at negative cash flow, but on the higher end I'm looking at ~$600/month cash flow (based on converting the 2x 1-bed units to 2-bed units.

If you get a MF property with all 1 bed units, I think you'll attract less families, so local schools won't matter as much but proximity to jobs and bus lines and restaurants etc will matter.

80 Yr. old duplex priced at ~$110,000 (reduced twice since December of last year, initial price listed at $135,000)Each unit is 1 bed/1 bath, total square feet living is about 970Taxes in 2018 were $515On the website it shows property tax as $43/mo and home insurance as $52/moAssessment was about $4,500 (why is the difference so large from listed price?)

@William Gillette one of the people I asked yesterday has a 4 bed 3.5 bath property available.
