Converting an owner occupied property is a preferred way to accumulate real estate assets over a long period of time. I always encourage potential sellers to consider holding onto propety they own and covert it to a rental as opposed to selling and then buying. Owner occupied financing is the absolute lowest rate as well. If it is not feasible then I understand. Additionally if your only source of a downpayment is the equity in the property I understand that as well. It may serve you well to sit down and pencil things out before you move forward with accepting an offer. Run some sample scenarios over the next year or two to see if you can get away with holding the property and being able to come up with the downpayment for another home. If not then I understand. If you have already done all that and made the decision, consider this response moot. Once you sell it, it is gone.
