Playbook
Expect competition, escalation clauses, and pressure to waive inspections. Make your strongest offer up front — Hot markets reward decisiveness, not negotiation. If you can't write a clean offer, you may not be the best fit for this market right now.
Price slightly above recent comps and let multiple offers work. Days-on-market should be short. Don't accept the first offer in the first 48 hours unless it's significantly above ask.
Cap rates are still workable thanks to a reasonable price-to-rent ratio. Buy-and-hold math works if the trend continues; underwrite a moderate slowdown to be safe.
