I own a double in which I rent out the upper flat.

I'd probably get a double security deposit though.

But of course your advice is still valid - I don't want to get burned so I'll double-check everything (valuations, sequence of events, etc.) with the assessor.

I bought a duplex for 13k and put 8k into it in heating system and remodel of attic to turn one of the apts to a 2 bedroom apt.

This will in essence actually double dip deductionsSince you paid cash you will not have an interest deduction.You do want to depreciate the property.

Good housekeeping is a S-8 rule and poor housekeeping can be a cause for inspection rejection and re-inspections.A single parent with 2 kids of different genders will qualify for a 3 bedroom unit and can be ideal tenants as there are only 3 people in a 3 bedroom unit.

A three bedroom dwelling can easily accommodate 5 or 6 people.

I paid 27k for a large 4 bedroom home near a college campus.

For example I bought a duplex several years back and it didnt cost much to convert attic to a second bedroom.

-furnace in master bedroom (again a code issue?)
