I have 2 model X and  a Y so I am ok waiting ..

But high upfront commissions in relation to insurance payments is not helping the insured.A high upfront commission by a real estate agent is not helping the house seller or buyer.A high upfront commission by mortgage broker is not helping the mortagee.A high upfront commission by the car dealer is not helping the car buyer.Each product has different remuneration model.

I’m wondering if anyone here has had success with this model and could share some strategies that worked for them?

Maybe I'm actually in the right model right now. 

We have a model-driven forecast for home price appreciation in the top 381 metros in the country, and we have two very out-of-consensus views as a result.

I like the mid term - short term hybrid model there.

I don't like the 20% down model, I prefer to BRRRR and then sit on that boring investment with little to no money in it. 

I could model what held-for-sale properties would potentially sell for and on a weekly basis adjust our model parameters based on what winning bids were for the week.

That’s not their business model.

I don't think it's a bad business model, a turnkey company marketing to OOS investors, but since I didn't do business with them, I don't know much about their homes.
