In June 2018 we bought an updown duplex for $625,000 ($289/square foot) with a 3.5% FHA out of a HELOC from our previous primary residence.

I have like $40k in reserves and access to my $50k HELOC.

I don't have the cash to put down any kind of down payment, so I'm going to get a HELOC for the equity in my house for the down payment and take a mortgage for the remainder.Any tips or advice to keep me from making mistakes taking on this much debt?

Cash from our HELOC (Home Equity Line of Credit) and savings How did you add value to the deal?

Should we put it back into our primary residence so we have equity to take out a HELOC? 

So we would need to take out a HELOC for most of the downpayment on the new place. 

or even a heloc?

Who is the best for heloc on investment property?

Also a lot of place are cutting their HeLOc origination and placing more restrictive guideline for people getting even a primary loan or HeLOc, how do you guys think this will Impact the market of RE???

Note that the high "other" expenses include $420 monthly heloc payment.
