I have a mix of completely paid off properties with no loans, paid off properties with HELOCs on them (presently unused for quick easy access to capital), and properties with low interest mortgages (leverage) on them.

If you used a heloc for the cash they will make you pay that back down to zero when you cashout. 

@Nick G. so the 10% would pretty much be a HELOC?

@Christian Allen there is no issue with you receiving a HELOC and then moving out.  

HELOC is revolving (like a checking account).  

I would say to pay that off with personal funds and get a HELOC on your primary residence to tap the equity.

@Joel Duguay - As already stated, the tax implications should be a non-issue on the sale of your primary residence.As an alternative to selling, you could also pull out a ton of equity with a HELOC and potentially have your cake and eat it too.  

I have an untouched $100k heloc on my primary.

You can use a HELOC on one of your other properties for all or part of the deal.Private and hard money can be used for all or part of the purchase and repairs.Some people use all cash. 

I ran into the ten financed property limit and my primary residence only had a HELOC on it.
