Quotes

✅“My red flag is just blindly putting numbers into a model, if you don’t understand how it’s calculated or how it affects your returns, you’re flying blind.”

✅“I’ve seen clients double dip, even triple dip on rent premiums, taking a property from $850 to $1,300 overnight. That’s not just unrealistic, it’s dangerous.”

✅“You can’t be blind on taxes. If you don’t plan for reassessment increases before you close, you’re stuck, and the county will take your property if you can’t pay.”
