Yes a 2nd position loan on the duplex, get what you need to do the renovation on the other property and leave the 1st alone.The other property, is it max leverage already?

Purchase price: $320,000 Cash invested: $55,000 Sale price: $320,000 Helped House hack for a cient of mine.

We're either looking at renting out our current SFH or buying a duplex and house hacking. 

For bigger renovations or repairs that require specialized skills, it’s usually best to bring in a pro.

Doing external renovations now and turning 2 vacant units.

I had lived in my house for about 5 years and had 60k in equity.

Other than rent issues, he keeps the house very clean and maintains the property decently. 

We live in an area where prices for houses around around $700-1,400 a sq ft (and climbing!) 

are utilities available, etc....You may be WAY past these steps, in which the funding question you are asking is spot on, but I caution you to make sure you are doing your due diligence to make sure the price you pay (up front cost, financing, excavating, renovation etc. all are worth the outcome.Let me know if you have any questions, I would love to help

(edit: the property can have up to 3 units built on it...house with attached separate apartment + unattached ADU)Of course, other people are telling me to park my cash in a high yield savings account and just chill LOL, but I'm not really comfortable with that either as an investment strategy.
