I think I had tenant move out like 2-3 months too late. 1031 wise, do I have to rent it out for 2 years in order to avoid cap gains?

Its needs a small bit of rehab to get it ready for rent.

When I rented my townhouse this spring I had numerous people begging for it.

The second floor is a 4-bedroom apartment that can rent for $2,500-$3,000 a month with $15k in renovations.

I feel like I only need to incorporate DSCRs, NPV, IRR and of course growth rates (both expense and rent). 

The issue I am facing is that the property is zoned for residential use only, and I am interested in renting out both the main house and the pool house as separate units.

Great investment getting ahead of the college housing expenses and putting the equivalent rent money to work..If the property is generating income it can be classified as a 'second home.'

When I travel for a boots-on-tour I NEVER rent a vehicle for this exact reason, I get a taxi(uber) everywhere and I simply talk to them, what good, whats bad, where should I go, where should I stay away from, whats happening, are things getting better, worse, what do you love about area, what do you hate.

Good evening everyone,how do I separate utilities when I have an ADU that is rented with a fixed utility price?

I rent SFR so almost all my tenants have kids.
