This is obviously location and property specific, but we're working with partial numbers so far...let's assume you'd want to stay in the cabin on vacation:)  If we find a place for $300k with 25% down at 5% interest, conduct $50k of value-add rehab...renting it 12 weeks/year breaks the project even on a cash-flow basis incorporating all costs.
