Why work with me

Three things worth knowing.

I built the room.

I founded VAMO Rising Professionals, a monthly networking event for Atlanta professionals, because the existing scene felt corporate and impersonal. It now fills a room every month.

Decatur raised, Va-Hi resident.

I grew up in Decatur, graduated magna cum laude from UGA, and live in Virginia-Highland today. My read on these neighborhoods is current, because I am in them every day.

In their words

Ten reviews. Ten five-star ratings.

Communicative, professional, knowledgeable, and genuinely invested in helping us find the perfect home. She was even able to find us an off-market home in the neighborhood we wanted to be in.

Mason went above and beyond to help us find our first home. She knows Decatur very well and helped us choose the best neighborhood for our commutes, routines, and hobbies.

Cole M.First-time buyer, North Decatur, 2025

She was our second realtor after going four months with no offers. Within 24 hours of listing with Mason, we had an offer for list price.

The honest answers
“Does the seller pay my agent?” Not exactly. I would rather explain that than dodge it.

Commission, closing costs, earnest money, down payment assistance: the questions people search at 11pm, answered in plain English before you sign anything.

Who actually pays my buyer’s agent?

Compensation is fully negotiable and seller-paid commission isn’t guaranteed anymore. Your buyer representation agreement spells out exactly what gets paid, by whom, before we look at a single house.

Do I really need 20% down?

No. Programs exist with as little as 3% down, and Georgia down payment assistance can cover a meaningful chunk of the rest. What you need depends on the program, and we would figure that out together.

What do closing costs actually run?

Plan on roughly 3 to 4% of your loan amount on top of the down payment, and some of it is negotiable to the seller. I will walk you through the real line items, not a vague estimate.

What if you think I shouldn’t buy?

Then I will tell you that. A client who waits a year and buys the right house is a better outcome than one who rushes into the wrong one.
