@Sean MacDonaldI think you summed it up in your observation of your clients, it's very typical here in the valley that the number of transactions will decline right before an election and then those buyers just like your clients will get back in and the number of transactions will pick back up in the months following the election.

However, when I thought about it, there was not any verifiable evidence to back up the stories.

:@Cody DeLong yeah, I've considered the heat pump with oil backup option.

As for getting a HELOC, it's prime + index (fluctuates based on the market), so to answer your question, if you are able to qualify by yourself, then it's always a better option to get a loan solo, then use your spouse's income as a backup for future investments. 

A solid single will build your confidence and teach you a ton.Know Your Exit Plan: Have a backup—rental, flip, or sell later.

If you can back up what you say with hard evidence, I move on.Leesburg!
