Ask Mark Seltzer


Mark helped me purchase my condo over 10 years ago and has kept in touch throughout the years. I had no hesitation about using his services again. He had my property pending in only about a day. Since I live out of state, he scheduled all repairs for me and did some minor fixes around my place. He goes above and beyond! Seriously, the best agent I've worked with.
