College rentals are great, but more time intensive and usually better managed by more experienced landlords because college kids break more stuff and don't know how to work a lot of things.

Deegan and @Arda Bircan There are technically 7 Tests for Material Participation (but 3 that are most common) -> the individual 500 hour mark, that the activity of the individual is substantially all, and that the individual participates more than 100 hours + no-one else spends more time than them.Litmus Test: Are your hours integral to the operationsThe hours that qualify must be substantially all hours and have a legitimate impact on the rental activities.Activities that generally count: showing the property for rent, taking tenant applications & screening tenants, preparing & negotiating leases, cleaning & preparing the units for rent, repairs, and improvements, managing the construction, purchasing supplies & materials, inspecting the property, responding to tenant complaints & inquiries, collecting & depositing rents, evicting tenants, writing & placing advertisements, and working on your websiteActivities that don't count: education & research, investor-type activities, and travel time..

(Especially during an intense work-out or something!)

If you can do conventional you do not have this test (but talk to a lender to be sure and get your specific situation). 

.- Married couples filing jointly can exclude up to $500,000 of capital gains.Conditions for Exclusion:- Ownership and Use Test: You must have owned the property and lived in it as your primary residence for at least two out of the last five years before the sale.- Frequency: You cannot have excluded the gain from the sale of another home in the two years before the sale of this property.For a duplex where you occupy one unit and rent out the other, the rules are slightly different:- Owner-Occupied Unit: The portion of the property you lived in qualifies for the exclusion, provided you meet the ownership and use test.- Rental Unit: The portion of the property that was rented out does not qualify for the full exclusion but can benefit from partial exclusion based on the proportion of time you lived in the property.

You'll want to test the paint surfaces for lead.
