Property Overview

304 Gruenther Ave is a substantially larger-than-typical Twinbrook Forest home offering approximately 2,504 finished sqft and multiple private living areas.

The main portion of the home is reported as a 5-bedroom / 3-full-bath residence, with two additional finished living areas providing another 2BR/1BA and 1BR/1BA physical configuration.

The home has already undergone substantial renovation, making this more of a finish, punch, optimization and configuration opportunity than a traditional full-gut project.

The size and flexible layout create a strong opportunity for a renovated retail flip targeting buyers seeking multigenerational living, in-law space, guest quarters, home-office flexibility, or private extended-family accommodations.

Main Residence

• Reported 5-bedroom configuration
• 3 full bathrooms
• Mostly renovated interior
• Updated kitchen
• Renovated living areas
• Fireplace
• Multiple living zones
• Flexible bedroom / office space
• Natural-gas forced-air heat
• Central A/C
• Updated windows reported

The home’s multi-level layout provides substantially more finished living space and room separation than the typical Twinbrook-area house.

Additional Living Areas

One of the property’s biggest differentiators is the amount of private secondary living space.

Additional Living Area #1

• 2-bedroom physical layout
• Full bathroom
• Private living space
• Separate rear access

Additional Living Area #2

• 1-bedroom physical layout
• Full bathroom
• Connected to the lower portion of the main residence
• Additional private/flexible living space

These areas provide potential utility for:

• Multigenerational living
• In-law suite
• Extended family
• Guest quarters
• Home office
• Recreation space
• Private living accommodations
• Potential accessory-living use subject to City approval

The additional living areas are not being represented as separately legal rental units. Buyer to independently verify permits, approved use, bedroom/bathroom configuration and ADU eligibility.

Condition / Renovation Profile

This is not a full-gut renovation.

The property is already mostly renovated, with much of the major cosmetic work completed.

Existing improvements include:

• Updated interior throughout much of the home
• Renovated kitchen
• Multiple renovated bathrooms
• Updated flooring and finishes
• Approx. 4-year-old windows reported
• Five physical full bathrooms reported
• Multiple finished living spaces
• Central HVAC
• Supplemental mini-splits
• Public utilities

Remaining work should primarily focus on finish work, punch items, corrections and optimization.

A musty/mildewy odor has been reported in the lower 1BR/1BA area. Buyer should evaluate the moisture source and remediation scope during due diligence.

ARV & Comp Support

ARV: $695,000–$720,000

At approximately 2,504 finished sqft, the target value equates to:

Recent renovated sales demonstrate strong support for larger finished homes in the Twinbrook / 20851 market.

1501 Bradley Ave — $695,000

• Sold April 23, 2026
• 5 Beds / 3 Baths
• Approx. 2,001 finished sqft
• Twinbrook Forest
• Very good condition
• Flexible lower-level / in-law utility
• Garage

This sale demonstrates that the Twinbrook Forest market can support pricing at approximately $695K, despite offering materially less finished area than the subject.

622 McIntyre Rd — $685,000

• Sold May 14, 2026
• 3 Beds / 2 Baths
• Approx. 2,407 finished sqft
• 8,519 sqft lot
• Fully renovated / turnkey

McIntyre is an excellent finished-size comparison and is approximately 100 sqft smaller than the subject.

Its approximately $285/sqft sale price translates to more than $710K when applied to the subject’s finished area.

1601 Forbes St — $675,000

• Sold March 27, 2026
• 6 Beds / 3 Baths
• Approx. 2,568 finished sqft
• Renovated
• Finished walkout lower level
• Secondary kitchen
• Separate entrance
• Multigenerational utility

This is one of the strongest functional comps due to its nearly identical finished square footage and flexible lower-level layout.

1627 Marshall Ave — $675,000

• Sold December 1, 2025
• 5 Beds / 3 Baths
• Approx. 2,461 finished sqft
• Fully renovated
• Strong retail presentation

Another near-exact finished-size comparison.

At approximately $274/sqft, applying the same price per foot to the subject supports a value around $686K, before considering the subject’s additional physical bedroom/bathroom utility.

7007 Lemay Rd — $799,000

Upper-End Retail Benchmark

• Sold June 24, 2026
• 4 Beds / 3 Baths
• Approx. 2,559 finished sqft
• Strong conventional retail layout
• High-quality finished presentation

At approximately 2,559 sqft, Lemay is an extremely close size match.

This is a superior and more conventional retail product, so it should be viewed as an upper-end market benchmark, rather than a direct ARV comp.

Its $799K sale demonstrates the depth of buyer demand for properly finished 2,500+ sqft detached homes in 20851.

ARV Positioning

Working ARV: $695,000
Strong Retail Target: $700,000–$720,000
Upper-End Market Benchmark: $799,000

The subject requires approximately $278–$288 per finished sqft to achieve the marketed ARV range, while recent comparable renovated properties have demonstrated pricing at and above this level.

Exit Strategy

Retail Flip

Primary exit as a large renovated single-family home emphasizing:

• 2,500+ finished sqft
• High bedroom/bathroom capacity
• Multiple private living areas
• Multigenerational functionality
• Extended-family / in-law utility
• Work-from-home flexibility

Multigenerational / Extended-Family Buyer

This may be the property’s strongest finished retail positioning.

The layout provides meaningful separation between different sections of the home, allowing buyers to accommodate extended family, guests or private living arrangements without requiring the property to function as a conventional multifamily building.

Accessory-Living Potential

One private living area may provide potential ADU / accessory-living utility subject to City of Rockville approval and permitting.

Buyer to independently verify all additions, kitchens, bedrooms, bathrooms, permits and approved uses.
