We drove neighborhoods, a practice known as “driving for dollars,” and looked for abandoned homes with overgrown lawns, newspapers stacked in the driveway, and exterior decay.

It's up to you but I would collect an addition security deposit because when they move out I can guarantee they will not lift a finger to fix the lawn.

Then while I was in Iraq he moved on my street and mowed the lawn for my wife.

It saves money in snow, lawn, and trash.

To Summarize:-shown behavioral instability on several occasions (Differing moods daily- outburst have increased in anger over time)-Refuses to follow basic guidelines-Parks on front lawn instead of designated parking lot- has damaged $$ front lawn-Has an entire list of repairs that he wants me to fix...

I claim mortgage interest, utilities, $1000 for lawn maintenance and property tax but I still fall short come tax season.

Hey @Armando Mejia, as @Andrew Meyer explained, you will definitely want to run your calcs based on both units being fully rented to tenants (including vacancy factor).Along with your PITI, you will also want to include all owner-paid recurring expenses such as water/sewer/garbage, an average maintenance expense (lawn, snow, general repairs), and long-term capital expenditures (new roof, furnace, etc).Once you are happy with your approximate monthly/annual cash flow assuming both units are rented, it will be easy to compute what your required living expenses will be if you were to live in one of the units.Be aware that typically a 3-plex or 4-plex will allow you to live for cheaper and cheaper in comparison to a duplex.

Do they care for the lawns?

So that 3 comps is artificially inflated the market,sometimes unnecessarily.The one that's really driving up the price is really inventory these days and/or the DOM.

( taxes, utilities, insurance, lawn/snow, etc.)
