Typically you'll need to have the house off the market for 6 months before financing will be available again. Rental/investment properties require better credit, lower debt to income ratio, and a lower loan-to-value than primary residences. If your debt ratio is hurting, then as long as you can provide a signed rental contract on the rental property then 75% of the rental income can be used to offset your debt payments.
