A condition of sale on your purchase offer, tied to your Rosewood home actually closing, is the most direct way to link the two, though sellers on the other side may prefer a firm offer, so it becomes a negotiation about who carries the timing risk.
Bridge financing is the fallback when the dates cannot be lined up perfectly, letting you access equity from the Rosewood sale before it formally closes, but a lawyer should review the loan terms since bridge financing costs vary by lender and by how long the gap runs.
Getting an accurate value on the Rosewood home early lets you plan both transactions with real numbers instead of guesses. Get your hand-reviewed valuation from Joel Dyck.
