These are difficult to finance on the private lending side, just FYI.

However, I want to make sure the homes are financeable to the end buyers.

need separate bank account and probably credit card; need to keep all the funds separate; need to get commercial financing so generally worse terms/rates (granted, right now rates are dislocated, but an 1% here or so over years adds up) and prepayment penalties; commercial financing I think generally comes with points where conforming loans don't have to have points; personally i find it a "drag" on funds since you need to leave money in the LLC(s) bank accounts for variety of reasons to operate and protect the corporate veil;

I'm wanting to get more creative in my financing strategies to reduce taxes and maximize profits. 

 Quick question about seller financing.  

Thanks for the creative financing choices Any more to add on this situation It almost seems like in any situation in order for her offer to be strong she has to have the cash in hand. 

Make sure you know the value the ADU will add to the property before building the ADU. 2) The financing on an ADU is typically far worse than for initial investment property acquisition or is often not leveraged (HELOC, cash out refi, etc).

How did you finance this deal?

Do the high rates have any affect on brrrr since you are perpetually financed?

I ended up using hard-money to make the purchase, financed in my LLC.
