While you may be eligible for a tax exclusion of up to $250,000 ($500,000 if married) on the sale of your primary residence, any period during which the property was used as a rental is considered "nonqualified use."

So for vast majority of the history where USA enjoyed position as net exporter, innovator, world currency standard, it was NOT a title held due exclusively to the USA "greatness" as we are all force feed.     

The cost of title insurance is dependent on (1) the state the property is located in (2) the amount being insured (3) whether insurance was recently purchased from the same insurer, (4) the exclusions in the policy.  

Either way, you need to take the legal steps to obtain exclusive possession. 

If it wasn't an exclusive buyer agency agreement there would be no contract to cancel because it would be by definition NON-exclusive.

For example, the “Home Sale Exclusion Gain” (IRS Section 121) lets you exclude up to $500,000 in profits if you are married filing jointly and $250,000 if you are single.The post originally appeared on the BiggerPockets blog.

To show a home, you must have either a non-exclusive buyer agency agreement (a one-off) or an exclusive buyer agency agreement signed with a client to show them homes.

Then use section 121 tax exclusion.

However, the use of the property as a personal residence by Person A might qualify Person C for a partial exclusion of capital gains if Person A met the 2-out-of-5-year ownership and use test before their death.
