What is the average cost of reporting to collections?

I'm open to new ideas to learn.I'm curious to know: what is a standard or average seller finance deal? 

Typically a rule of thumb is with no experience and average credit you are looking at 15-20% down depending on the rehab size and complexity. 

We cash flow on average $3K a month once leased on a 3-5 year commercial lease with increases built in.

This was an issue that was undetectable and unforeseeable to the average person and it caused damage.

The support was solid, and the biweekly meetings were productive.

We have a portfolio of homes we lease to assisted living operators that cash flow on average 3K a month.

Lets say that their coaching was for a year and it cost them $10,000 and the average student bought 2 homes in the year and gained an increase in equity by $80,000 and they felt that they were confident in finding and purchasing good deals after the year was over.  

Some attractive destinations there can easily achieve 15% ROI, and average property prices can be as low as 250k so it's an easier entry point.A lot of my friends invested in Bali and had great returns, especially if they've invested before the pandemic boom.

Personally my stock portfolio (mostly very safe, set and forget/ "lazy portfolio", un-speculative "aristocrat stocks" and some basic high dividend yield ETF's like Vanguard's VYM which pays 3% dividends and has a 30 yr. average compound return of 10%) is doing much better than if I were to use those funds to pay down my very low interest, not at all over-leveraged real estate debt.
