Another big aspect that will help you avoid vacancy would be to ensure you are renting your property at a reasonable rate, which you can determine by looking at what is renting or has been rented around your property!

As Charlie said, I would avoid the FHA route specially if you're planning on this being used as a investment property.

He would like to attempt to avoid paying capital gains tax.

There is only one problem I have with BP and that is many investors post how they would invest and what to avoid without considering the market.

My understanding is that reassessment can only be avoided by putting the property in a trust.

If you give them a chance to pay on their promise date and they were being truthful, you will have avoided a lot of time and cost associated with filing the eviction and then cleaning/fixing up the unit, marketing, and not to mention vacancy.

Your could rent it out for a couple of years to avoid any red flags with the tax man.

The buyer also gets the benefit of avoiding other underwriting standards and the associated processing delay that comes with.

I recommend your lease include a minimum 3% annual increase so the tenant is always expecting it and you avoid falling too far behind.Give them 3% or $25 or something to that affect and they can either accept it or move out.
