Planning an ADU & Raising Capital

[Luke Masaschi]

So I recently did a BRRRR and am currently renting the home as an STR. I made the decision to turn the unattached garage into an ADU making the deal very very good once done. I have already ran all utilities from my original rehab budget but need about 30k more to finish.

Now im 22 and really took the gamble putting most of my money into the original deal so savings isn't really an option. I can slowly get the money / 0 APR first year cc/ ask friends and family to borrow. I could also use my cash out refinance to complete this as well but I also wanted to get into another brrrr and this may slow me down using all my cash without really being able to pull it out unless I HELOC after completion.

What would you guys do?  I really would like to keep as much personal cash as I can at the moment because I am expecting some very big life changes this summer which will take a good chunk of my income. I have another property and a W2 job.
