Long story short I purchased a home in an overinflated environment for $500k.

That's a powerful story @Jeremy Beland! 

That's where the story should end.If they continue to complain, ignore them because the solution was already provided.

Telling you the whole story;  I still see now and then my personal reply to a seller who decides to reply to the multi month multi touch campaings that are built into this creative system, that the system sends out 3,4,6,8 msgs asking in different ways if they want to sell, if they'd like me to call etc etc, so they say; sure whats your offer. 

Pompano FL ,AT least quadrupled in price over the last 10 years Cincinatti great returns over 10 years, Indy Great returns and still doing well, Akron Cleveland, Tripled, quadrupled or more on value on top of 25-30% NET incomeWe were told we were crazy 10+ years ago, from the internet, well how wrong were all the experts :) Amazon now has 2 mill sq ft, Sherwin Willams built a massive 30 story new headquarters in the middle of the city, new Hotels, massive infrastructure and so so much more.

But when disputes arise it's another story entirely.

However, find out their story.

From 6 years of being in real estate, I’m far from an expert, but the three regrets I hear the most are:1) I wish I started sooner2) I wish I bought more3) I wish I never soldMy takeaways from these stories are1) Start today2) Buy Smart3) Think long-term

From Dallas to Houston, Austin to Waco, each metro area tells a different story.

Not something I have experience with, but I know there are a lot of resources out there and I have heard many success stories.
