Hopefully you're able to make many connections with investors and learn a good deal about different strategies.When it comes to financing a first deal for an investment property, I may recommend purchasing the property first in your own personal name and trying to get as low of a rate as possible.

Or does it all depend on the LTV ratio on the HELOC as to how low the interest rate will be? 

Thee richest of the richest globally will put 100% of their funds towards USA assets.

The market rate for something you are talking about right now is about 9.85%-11%, 1-2 points, and doc fees totaling about $1k-$2K.

Paid back as those properties in the fund sell and above initial LP payback.  

Great for rates.

With the high rates we are at right now, I would probably suggest a shorter term adjustable rate mortgage with the intent to refinance it down the line (presuming you think mortgage rates will eventually fall back down).  

As long as the projected rent from the ADU covers the monthly payment (typically 1.0–1.25x), you can qualify.We’ve recently done DSCR deals with rates as low as 7%, depending on factors like credit score, leverage, and property type.

Then finding a Joint Venture to fund the property.

Maybe Breclaw Capital is super real and it is real private capital from an individual with low origination and fair rates.
