Donna Wisniewski at Long & Foster in Baltimore: Buyer's Agent for Federal Hill and Inner Harbor Sales

Donna Wisniewski is a Long & Foster real estate agent based in Baltimore who specializes in buyer representation for residential properties in Federal Hill, Inner Harbor, and surrounding central neighborhoods. She works on commission (typically 2.5 to 3 percent of the sale price paid by the seller) and represents buyers navigating a market where Federal Hill townhouses often list between $450,000 and $650,000, while Inner Harbor condominiums range from $300,000 to $700,000 depending on unit size and building amenities.

What a buyer's agent does and how Wisniewski fits the model

A buyer's agent negotiates on behalf of the purchaser, not the seller. Wisniewski identifies properties matching your criteria, arranges showings, reviews contracts, and advises on offers. She is paid from the seller's proceeds only after a sale closes, creating an incentive structure where her commission exists whether you buy or not but increases with the final sale price. This differs from a seller's agent (who lists the property) or a discount brokerage (which charges flat fees or reduced percentages regardless of outcome). Long & Foster, founded in 1968 and operating across Maryland and the Mid-Atlantic, is one of the region's largest brokerages and gives Wisniewski access to the Multiple Listing Service (MLS) shared by competing agents.

Commission structure and alignment with buyer needs

Wisniewski's commission is negotiable. Standard practice in Baltimore is 2.5 to 3 percent split between buyer's and seller's agents, meaning she typically receives 1.25 to 1.5 percent of the final price. Some sellers offer lower splits or no buyer's agent commission; in those cases, Wisniewski may negotiate a flat fee with you or decline to show the property. If you work with her as a buyer, you do not pay her directly out of pocket unless you sign a separate agreement (which some agents request for new construction or unrepresented sellers). The risk for buyers is that her payment depends on closing price, not your financial outcome, so a second opinion on valuation or negotiation strategy is prudent.

How to evaluate Wisniewski against other Baltimore buyer's agents

Long & Foster agents are accountable to a large firm with compliance staff and dispute resolution processes, whereas independent agents or small brokerages may offer more flexibility but less institutional backing. Wisniewski's specialization in Federal Hill and Inner Harbor means she likely knows recent sales, tax assessments, and neighborhood-specific contingencies (flood risk near the harbor, condo board approval timelines, parking costs). Compare this to a general-market agent covering the entire city, who may handle more volume but dedicate less focus to your specific area. Interview at least two agents before committing; ask for three recent transactions in your target neighborhood and permission to contact those buyers.

Services Wisniewski typically provides

As a buyer's agent, Wisniewski identifies properties, schedules tours, conducts comparative market analysis (CMA) to justify offer prices, drafts and submits offers, negotiates counteroffers, coordinates inspections, and ensures contingencies (financing, appraisal, inspection) are met before closing. She does not conduct the inspection, arrange financing, or conduct the title search, but she coordinates the timeline and alerts you to red flags. She also advises on whether a property is overpriced relative to recent comps (comparables) in Federal Hill or if it has structural or title issues that affect value. She cannot provide legal advice; a real estate attorney (required by Maryland law) handles contract review and closing documentation.

The first steps with a buyer's agent

Initial consultation is typically free and conducted by phone or at a coffee shop. Bring a pre-approval letter from a lender stating your purchase capacity and down payment amount; Wisniewski will ask for your budget range, neighborhood preferences, must-haves (parking, outdoor space, number of bedrooms), and timeline. She will explain the offer process, the role of earnest money deposits (typically 1 to 2 percent of offer price in Baltimore), and contingencies. She will then add you to her email list for new listings matching your profile and may send you a CMA to calibrate expectations.

Hours, contact, and next steps

Long & Foster's Baltimore office is open Monday through Friday, 9 a.m. to 5 p.m., with limited weekend hours during active seasons. Wisniewski's direct contact information is available through Long & Foster's website or local real estate listings. Verify phone and email directly rather than relying on third-party directories, as agent contact details change. There is no parking fee to meet her in person at most offices or at properties.

Wisniewski suits buyers new to Federal Hill or Inner Harbor who value neighborhood expertise and do not want to pay upfront fees. She is less suitable for buyers who have already negotiated directly with a seller or for those seeking a discount brokerage model. Long & Foster's scale and MLS access make her a credible choice in a market where personal relationships and access to off-market deals still drive outcomes.
