Advice on home rehab loan vs hard money

[Matthew Fermino]

I am looking to build a two bedroom in the apartment to move my mother into our home but have a separate space for her. I am selling the condo I have that she currently lives in and doing a 1031 exchange into another investment property. I don't think there's a way to roll any of that money into an Inlaw suite so I'm looking for the best way to finance this. I don't have quite enough equity to do a HELOC as I owe about 675k and current value is about 950k.

Estimates from my contractor who I’ve worked with in the past is about 175K for the addition.  I was considering options like Hardmoney (never done this) home improvement loan (never done this) or Finding a credit union or bank that would give me the a rehab loan based on the post rehab value loan (never done this either)

Any advice would be super helpful, I’ve got a lot of balls in the air right now. Thanks in advance as always
