I am just curious how most structure their payment process when receiving and paying rental payments, vender payments, etc.

It can be a great alternative to traditional bank loans, offering flexibility in terms of both loan structure and timelines.

What types of funding structures have you found most effective for scaling your real estate portfolio? 

Thank you Ned, that is exactly right, we actually check a condo/townhouse about 2 weeks ago, the thing was a condo with a basement, I cannot tell if it was a condo or townhome, anyway, the ceiling in the first floor was bowing, the 2nd floor, one of the bedroom was sinking, could not tell how this damage was done but the walls came apart from the floor, you could see the roof of the unit bowing inwards towards the structure a bit, and their "general contractor" estimate that for 5k they could straighten the property and level everything, even 1 window and 1 door looked so uneven that you would think  there was something wrong with your eyes...5k for structural damage, good luck with that one, we ran as far as we could from that....but we have seen they do inflate their ARV, since we learned the hard way , we go through these deals with a magnifying glass, I knew I was not so picky, numbers do not lie.Another thing that caught my attention, which I do not know if I am overly suspicious now that I am older, but they want to get the closing for us at the same time/day they are getting the property from whoever they buying it, which it seems to me they try to save on the closing by having a "dual" closing when in reality is just 1 closing and we are the one paying for it...I do not know there are few things that do not click right with this folks.

Additionally, they may include a carried interest or promote structure on the back end, which serves as an incentive or commission if they exceed performance expectations.Limited partners (LPs), on the other hand, simply invest capital and remain on the sidelines.

CA doesn't recognize series LLCs, so yes, you would need to be careful with costs for any structure that you put in place. 

However, if I'm just looking at the structure/improvement I believe that a home would depreciate following a curve in the same way that most physical goods depreciate on a curve (in terms of real dollars, adjusted for inflation). 

If so what's the best way to structure or creative ways to structure if purchasing multiple homes?

. - From what I understand, just because you can build an ADU by right doesn't mean you can build whatever structure you want.

That is an awesome way to structure during off season!
