Or is there a more efficient method to do this?

It is fairly basic compared to other changes in accounting method.

I would suggest they understand various strategies/methods to invest in real estate and then let that drive their next steps as opposed to the dollar amount they have to invest.

looking for suggestions on best methods/websites for marketing a long term rental.

My clients with $200k-$250k cash are able to get much, much higher ROI on real estate investing than what you're considering through some creative methods. 

I am here to learn about real estate investing especially the BRRR method.

My company bought dozens of properties using this method and I was sure we didn't overpay.

What are the pros and cons of each method?

I don't consider these funds liquid or available for REI usually because using that money for my own deals would require withdrawing it and paying penalties.

With the little knowledge that I have on this method, I started building it as if they were flipping a property... - They put in 2/3 of the money- Monthly payouts of 50% of profits- 4 month termBased on the pro forma of the rental, they'd have around a 30-35% roi by the end of the term.
