For lease option, since you agree to a predetermined price earlier, can't you wait for the market to go up, and then buy at the cheaper pre determined price, assuming real estate does go up in price?

I would definitely choose Fast and Good - as long as they stick to a predetermined budget I'm fine with paying what its worth. 

(I’m assuming these are private money lenders like you said because if they’re an actual hard money lender the rate/terms are probably going to already be pre-determined and they’re also likely only going to be willing to do first position loans.

Interest rate will be pre-determined/selected prior to funding escrow.

If they aren’t out by the predetermined date, we have an agreed upon rent payment (usually higher than market) that is deducted from the proceeds for every month they stay in.

Do you have predetermined topics/speakers?

Although its high interest rates scare some people away it is very useful in that it is usually lent against the value of the proprty and not based on some predetermined credit score.

.- There are covenants that cut him out if things start to not go well.Which, technically, is another way of saying that I'm buying the property, allowing him to work on it, and he's buying an option to purchase from me at a pre-determined future date and price.As a lender, that's the only way I'd do a debt deal at that LTV.  

If you make decisions, or if you predetermine future events based on the way they "sound", you are going to miss out on a lot of great opportunities.If the first time anyone heard any of the following statements:1 - I can build a set of monkey bars, out of wood, wire and cloth, and it will allow me to fly,2 - I'm going to take a bunch of "1's" and "0's", string them together in different patterns, and it will allow me to think about anything faster than the speed of light.3 - I'm going to eat a white oddly shaped ball, that came out of a chicken's....and it will taste great.4 - I'm going to collect and drink a whitish liquid that a cow had sprayed on the ground, and it will taste great....the words, "it sounds too good to be true" were overheard, and none of the above were done because everyone that heard those words believed them, we may never have the use of a computer, and airplane, and would not have been able to eat breakfast when hungry.Money doesn't make a noise, so money decisions shouldn't be based on what you hear...but by what you see.Credit cards work, if you are disciplined enough to work fast enough to pay them off before the interest kicks in.  

The owner/seller/vender takes a mortgage on a property in which they are also the vender.Rent-to-own can mean a variety of things:At one end of the spectrum you have a standard Lease (rent) with a separate Option to purchase (own) the property at a pre-determined price within a specific window in the future.
