Contra Costa CA ADU House hack

[Jason Brooks]

ADU on unincorporated contra costa California

large lot 9000 sqft lot

1300sqft primary house

adding 950sqft modular home

Loan on property: 418k
Property appraisal in the area same size: 580k

I want to refi the property into a va loan in order to pull out 100k taking the loan to the 90% loan to value maximum and have an adu installed. Has anyone done this? Do you all have any insight? I'm looking at bayarea manufactured homes(150k) and homes direct out(130k) of Sacramento. I talked to aduhabitat(259k) and they were amazing but there homes were 50k more than the other options. They look nicer. But I don’t see this area homes appraising for much more than 600k. adding an adu 3bdr 2 bath im hoping will raise my home value by at least 100k and I should be able to rent the adu for at least 1500 per month. And it will cost me an additional 500$ per month to take out the 100k cash out refi.

has any one done anything like this. any tips tricks or insight. thanks.
