So I am not saying that lease options are illegal or scammy.

You need to be careful around the risks of sudden price changes, market stoppages and watch for transaction fees.

When your in Transactional Real Estate like we have been and its been quite good since the GFC  cash flow at 200.00 a door has no interest for us..

And these were Portland Metro assets so NOT low value mid west assets.. we did this until the law changed and it was illegal to buy pre foreclosure and rent back here in Oregon..

Likely just raising it above market rent would be considered stupid, not illegal because then you’d have a vacancy.

Does Bigger Pockets have a calculator that can accommodate other loans that are part of a purchase transaction on top of the mortgage to calculate ROI?

There is nothing illegal as long as the property is zoned correctly.

I am a local agent and represented myself in the transaction.

If you're looking to transact faster than that, then your only option will be private Buyers.Another alternative, other than the ideas mentioned above, might be to sell part of the land into permanent conservation.
