What are you solving for?
Buy, sell, rent or invest. Tell us the goal. We'll find the path, with the math, and share it with your financial advisor, CPA or attorney.
Five-star service, backed by math.
Sell or rent? We find the sale price where they tie.
Both paths, built the same way on your numbers. Then we name the one input that could flip the answer.
What's my place worth?
More than a ballpark: a private market analysis of your home. Not ready to list? Start here anyway.
Find it, then run your numbers
First home, rental or value-add. We find it and run it through your numbers: payment, cash flow or IRR.
Ask us anything
HELOC or sell? Inherited a house? What can I build on this lot? No question too weird.
More sales and more leases in 2026 so far than in all of 2025.
Team totals for Conor and Monica Doyle, May 2025 through October 4, 2026, including transactions closed while affiliated with a prior brokerage. Closed sales count the full price of each sale in which Conor or Monica represented the buyer or the seller. Active listings are the sum of the published list prices of the for-sale listings below, including listings shared with the McCann Commercial team at Keller Williams Main Line; listings without a published price are not counted. Leases count one unit let to one household; 2026 is through October 4. Under contract is shown at the list or contract price, and one contract price not yet disclosed is not included; a sale under contract has not closed and may not close. In the news: Philadelphia Business Journal, July and August 2026 (two team listings). Sources: MLS, LoopNet and Crexi listings, public deed records, settlement records and our transaction files.
Five-star service, in their words.

“I had an excellent experience working with Conor to find my new home. He was professional, knowledgeable, patient, and always willing to go the extra mile to make sure I found the right place…”
“…When a property of interest hit the market he went above and beyond to set up a tour of the home within hours of it being posted. While the offer to close period was only 19 days and things were moving very fast Conor was there to assist…”
“…I was originally considering selling my home, but he walked me through the numbers and strategy in a way that made it clear renting it out was the better move for my situation…”
“Conor and Monica are amazing people they really know their job and the area.. Any questions I had they answered even if they were silly questions…”
“Conor has been fantastic to work with, he's a brilliant problem-solver with smart, creative ideas. He's honest, transparent, and executes quickly…”
And from clients we advised.
“Six Ten provided exceptional guidance when I considered converting my current property into a rental… Unlike most agents who focus primarily on closing sales, Six Ten delivered an honest review of all options, clearly explaining their assumptions and highlighting conservative versus optimistic projections.”
“The Six Ten team was instrumental when I debated whether to sell or rent out my place… What stood out was their objectivity. They didn’t push me toward a quick sale… In the end, I chose to sell my home, and I feel great about it.”
“What really set Six Ten apart was how they started, not with listings, but with a conversation about my goals, my budget, and what I envisioned for this next chapter… I genuinely felt like I had a team in my corner.”
“…They dug deep, analyzing the numbers and comparable properties, saving me from making an expensive mistake by advising me to pass on the property. That kind of transparency and guidance is rare…”
“As a CPA, I tend to approach real estate decisions with a strong focus on numbers and tax implications… I was incredibly impressed with the depth and clarity of their analysis.”

Estimates and analyses are not appraisals and not tax, legal or investment advice. Nothing on this site is an offer to sell, or a solicitation of an offer to buy, any security or investment interest. Commissions are negotiable and not set by law. Outside PA and NJ, we analyze the deal and refer you to a licensed local agent. In that case we are generally paid by the agent you use, through a referral fee their brokerage pays ours out of their commission. It is not billed to you separately, and we tell you about it when we refer you.
