I think that a heloc could be a great option for you. Like Ian said, they are easier to get when you currently live in the property (its your primary) and you will get a better % rate and higher $ amount vs doing it once it's a rental. You can move out right after the heloc is signed and it will still be valid and legal. I have talk to my lender about this strategy and had no issues getting the heloc right before I moved out and turned it into a rental. You can use the heloc towards the purchase of a new home. If your debt to income ratio is tight for the next home, you can try to get your current property under a signed lease before your loan closing date (even if the lease will not start for several months after you close, they just need a copy of a signed leased with the rent amount). The bank will subtract around half of the rent amount from your mortgage amount which will allow you to qualify for a bigger loan (because you will have a better debt to income ratio). For example, if you have a $1,000 mortgage and rent is $2,000, your monthly debt for that mortgage would be considered around $0 by the bank. This way, the bank will just be using your current income to determine what loan amount you are eligible for and your current mortgage will not negatively impact you. The other reason why I like this strategy vs selling and buying two properties is because it's much easier to get loans for a primary. Your second primary home loan should only required 5% down and you might even be able to do better with a VA loan. If you sell and then by two properties, you will have to put around 20% down on at least one of the properties (because it will be considered an investment property) and the loan rates are typically a little higher for investment properties. I would hate to loose that low interest rate you currently have. Also, rates could be up in 1-2 years.
