Using HELOC as cash reserves

[Ryan P.]

Does anyone know if it is generally acceptable to a lending bank to use my (primary residence) HELOC as proof of cash reserves when applying for a rental property buy and hold conventional loan? Or do you need to show proof that you have X months amount of cash in an actual bank account?

This post addresses HELOCs & reserves but isn't exactly on point: https://www.biggerpockets.com/renewsblog/2011/04/0...
