Troy Whalen

I'm Troy Whalen. I run The Discovery Bay Market, streamlining how real estate changes hands in this community.

Type any address in Discovery Bay.

What it is, when it last sold and for how much, from the Contra Costa County record and the MLS. Then do the thing, right here: write an offer, name your own price, see what could be built.

Public record only. Nothing on this page says what a home is worth; that is Tim's job, and you can ask.

How claiming your home works

  1. Find your home. Type your address. It comes up from the county record: the beds, the baths, the lot and every recorded sale.
  2. Tap This is my home. A free account and three fields. No listing, no sign, no obligation, and nothing about it is shown to buyers.
  3. It is saved, with your credit. Your home lands in your account with a $5,000 commission credit toward your next move. Keep it for your own sale, or share it with someone planning a move.
  4. Everything inside. Understand your zoning and what you could build. Local business pages and messaging with home services, and exclusive offers from local businesses.

Claim your home.

Save your home to a free account. Inside: a $5,000 commission credit toward your next move, yours to keep or share, your zoning and what you could build, local business pages and messaging with home services, and exclusive offers from local businesses.

How The Exchange works

  1. You list it, occupied. Price, rent and lease terms, visible only to investors holding an account. The tenant is not told, not shown, not disturbed.
  2. Every investor here sees it. It goes to every investor holding an account in Discovery Bay — people who want a rental that is already renting.
  3. Sell it with the tenant in place. No vacancy, no staging, no showings on a Saturday. The rent keeps coming through escrow; the lease transfers at close.
  4. 1031 into the next one. Roll the proceeds into something bigger, newer or easier within the exchange window. General education — the timing and the tax are your CPA’s call.

Buy or sell a rental without emptying it.

Owners publish price, rent and lease terms; investors hold a free account to see them; the tenant stays in place through the sale. The map is every investor-owned home in 94505 from the county roll, and the ones listed for exchange.

How buying a lot works here

  1. Every lot, ranked. Scored from the public record on lot size, the age of the home, years held, what the owner paid and whether they live there. Listed or not.
  2. See what could be built. Floor area, footprint, height and setbacks from Discovery Bay’s own zoning code, plus ADU and SB 9 lot-split potential under state law.
  3. Run the numbers. The Developer Comp Report: new-build sales and the top sales nearby, then teardown and fix-and-flip models where every number is a slider.
  4. The owner, approached. With a buyer agreement and your price in writing, Tim writes to the owner for you, even when the lot isn’t for sale. A home listed with another broker is approached through its listing agent, never the owner directly.

Every lot in Discovery Bay, ranked for what it could become.

Lot size, age, years held, last sale price, who lives there, zoning. Filter, rank, and hot-list the ones you want; Tim runs the Developer Comp Report on your list.
