So if your real gain was $105K or less you will pay tax on all of it.There are a couple of things you can do to mitigate.1.

If you rent month-to-month, you get 30 days notice any time of year with nothing to mitigate your risk.There's a big difference between "charity" and offering a discount to reward good customers.

It means you're looking at exit strategy and risk mitigation both, which kind of go hand-in-hand anyway for this situation.

Use the education to mitigate your risk.

An asset protection plan that ensures your other investments are separate can assist with mitigating some of the risks here.

You do not have to accept the tenant they bring you, but if they move out you have a legal obligation to mitigate (minimize) your losses.

I like talking with people that think about mitigation to risk and have limits in place to protect themselves. 

Mostly just Iowa law stating landlord must attempt to mitigate their losses by re-renting unit as soon as possible. 

Prepare the unit and re-rent it as soon as you can to mitigate your loss.Compensate your loss by keeping the security deposit (since it's allowed by the terms of the lease).

From the day we take title you then have 180 days to sell the properties you want to exchange into this new property.Reverse exchanges can be a great way to lock up your new asset first and mitigate some of the risk associated with trying to get someone to give you a contract contingent on several sales.
