My guess is though that as you and I suspect it is the "flovor of the day" as you say and a pretty bad flavor at that. 

It's the best model I have ever seen for turnkey.

Also, you may charge a premium on the rent (higher rent) in this model of leasing.If you charge them a higher upfront option fee, it will demonstrate that the buyer is committed reduce the likelihood of default.

Build a Scale model and see what it takes to get to your number.  

It was previously listed for-sale and for-rent when i got tired of the short-term rental model hassles and fees.

This model seems to work very well in that market.  

Here’s what I recommend:Cash Investments:No Debt, No Stress: With cash, you avoid third-party control and loan vetting, giving you full control of returns.Equity Builders: Partnering with builders often reduces your property entry cost by up to 20% below market value.Consistent 10% Returns: With an all-cash approach, achieving 10% ROI is realistic and efficient.Financing Strategy:If cash isn’t feasible, consider a balanced financing model:40-50% Down Payment: Keep leverage manageable while maximizing returns.Lower Debt Exposure: A conservative loan-to-value ratio (LTV) reduces risks and keeps returns stable.Work with a Builder: Collaboration with builders can lower acquisition costs and increase your ROI.Key Takeaways:If possible, prioritize cash for simplicity, control, and consistent returns.Financing can work well with a disciplined approach to debt and a strong underwriting process.Partnering with builders offers opportunities to reduce costs and enhance your portfolio’s profitability. 

It's hard to say if a 60k house is worth 40k or 80k, that's within the margin of error based on how much do you consider condition in your valuation.The % based agent commission model does not make any sense below 100k.

For that reason I built a full-functioning cash flow model taking into account hard money, the mortgage refinance and all relevant operating expenses to assess monthly cash flow.
