Hi @Cam Chan!

But listen, we have no kids, very little revolving debt, a big cushion of savings and capital, and Id like to think a firm grasp of know how on the industry (I’m a residential realtor).

@Cam JimmyAwesome, thanks for the insight!

If the interest on the investment property's HELOC is not able to be written off, would it make sense to consider an All In One loan instead (which is considered a 30 year note but is revolving simple ave. daily balance interest ) instead of the HELOC?

If STNL and tenants pay the taxes it can still affect their ability to operate the business and be profitable with all in costs.For MTNL the CAM above base rents lots of single operator to mulit unit inline retail tenants cannot absorb high property taxes that pushes their all in rent with cam too high to stay open.

I don't know for sure but my guess is having one thermostat for two units isn't to code, and if that is mickey moused together my concerns would revolve around what else is cobbled together DIY. 

Your credit score can be maintained at a good level by having zero balances across credit cards or any other revolving credit.

The benefit to a HELOC especially on a primary is you can typically get a higher LTV and it also acts as a revolving line of credit where you only pay interest when you actually use it similar to a credit card.
