@Jason D. Says it perfectly with over-leveraging can get you into trouble during tough times. The cash-out refinance we did on our one rental was only up to 70%, we got most of our money out of the property and within 6 months had the rest.
I like the HELOC since you do not need to use the money, it is only an option. Just make sure that when the HELOC ends that it does not turn into some type of mortgage product.
@Daniel Pitner Depends on the lender, I have heard people getting up to 100% on a HELOC if it is their personal residence. For an investment property, we have been able to get up to 80% on a HELOC.
IMO, I would rent the property out since only having 18k in equity if you sell it at 188k, you most likely would lose money when you factor in your closing costs from purchasing the property, your holding costs when you lived in the property and then the fees associated with selling the property.
If you can manage the property and make a return on renting the home I would do that. I would buy a new home and put 20% down or as close as possible. Then get a HELOC on my new primary residence to use in case I wanted to invest in a new property.
Shop around for everything, insurance rates, mortgage rates, HELOCs, renters.
Anything else let me know. I have a higher risk tolerance since I am young at 26, don't have kids, have not too many bills, make a decent income, live pretty frugally and my sister who is younger than me, smarter than me, makes more money than me and is better with her finances is a 50/50 partner. This may make my course of action different from yours.
