Overview

Greta Costa is a real estate agent with Howard Hanna Real Estate Services, working out of the company’s Xenia office. Her brokerage profile carries the tagline “Get Moving with Greta” and lists the designations MRP and SRES. Her recent MLS activity is concentrated in Beavercreek, in the Dayton area’s eastern suburbs.

In the period since March 2026, Costa has closed 3 sales with a combined volume of $1,188,500. All three were listing-side transactions, meaning she represented the seller each time.

She also leads Team Underwood Costa, a Howard Hanna team that includes Thomas Underwood as a team member. The team operates from the Xenia office, and its page describes the pairing as two dedicated professionals with global real estate experience.

Sales record in numbers

Costa’s three closed sales since March 2026 total $1,188,500. Every one of them was a listing sale: 3 listing sides and 0 buyer sides. Her prices ran from $270,000 at the low end to $637,500 at the high end, with a median of $281,000.

The spread is worth noting. Two of the three sales sit close together near the lower end of that range, while one closed at roughly double the median. Together that suggests a mix of ordinary single-family homes and at least one higher-priced property, rather than a practice focused on a single price tier.

On her listings, the median time on market was 37 days. The median sale-to-list price ratio was 98.6%, meaning homes typically sold within a little less than two percent of the asking price. One of the three listings, 1 of 3, sold at or above its asking price.

None of the three sales was new construction or a renovated resale, so the shares for both categories are 0%. She had no multifamily sales in the period. Her work in this window was resale housing, sold the conventional way.

Where she works

All three of Costa’s closings were in Beavercreek, a Greene County city east of Dayton. She had no sales in the city of Dayton or in West Dayton during the period. Her office is in Xenia, and her business listing names Xenia as part of her service area, though her recent closed sales were in Beavercreek.

The Beavercreek median sale price is $325,000. Costa’s median across her three sales there was $281,000, about $44,000 below the area figure. That reflects two of her sales closing in the $270,000 to $281,000 range, below the area median, while the third, at $637,500, was well above it.

Put another way, her sales covered both sides of the local midpoint: a pair of homes priced a bit under the typical Beavercreek sale and one in the upper part of the market. With a sample this size, the figures describe a few transactions rather than a pattern, but they do show she has handled listings at more than one price level in the same community.

One of her Beavercreek listings is also visible in the Dayton REALTORS MLS feed, credited to Howard Hanna and Greta Costa.

Background and credentials

Costa’s Howard Hanna profile lists two designations: MRP and SRES. The SRES designation is the Seniors Real Estate Specialist credential, and the team page refers to certified senior real estate specialists among its credentials. The same page mentions military relocation professionals and certified property staging experts.

The profile lists a broad set of specialties: estate properties, farm and ranch, first-time buyers, historic homes, investment, military, move-up, new homes, property management, relocation, residential and retirement. Those are the areas she names for herself. Her recent closed sales were all residential resales in Beavercreek, so they reflect only a portion of that range.

Her business listing on Yelp describes services that include acting as a buyer’s agent and listing agent, as well as rental agent and property management work. Her personal website is gretacosta.howardhanna.com.

Team Underwood Costa’s page states that the team brings 17 years of combined service. That figure belongs to the team as a whole and is not a measure of Costa’s individual tenure.

How the numbers fit together

Taken as a whole, the figures describe a recent run of three listing assignments in one community. Homes took a median of 37 days to sell and closed at 98.6% of list price, close to asking in a market where one in three listings reached or passed its list price.

The dollar volume of $1,188,500 is driven in large part by the single sale at $637,500, which accounts for a little over half the total. The other two sales together make up the remainder, with a median price of $281,000 among the three.

Her listed specialties include buyer-oriented areas such as first-time and move-up buyers, and her service listing includes buyer representation. In this window, though, her closings were all on the seller side. Whether buyer-side work appears in later periods will show up in the MLS data over time.

No leaderboard rankings are available for Costa in this window, so there is no local ranking to report. The figures above, her own price range set against the Beavercreek median, her days on market and her sale-to-list ratio, are the clearest measures of her recent work.
