@Adrien Schebott ok I'll answer that. You said:
Is paying $10 enough to give you equitable interest?
Does not having the ability to close make the contract non-enforceable since you can't hold up your end of the contract.
Assuming those two questions don't matter - does an equitable interest give one a right to market the property (like a RE agent does) before taking title? This is what gets wholesalers into trouble.
From what I have learned as long as the seller agrees to the contract and signs off on it yes it does, but I think your question is really hitting at that very low amount to gain that interest. At the end of the day the investor is looking to achieve maximum profits with minimal risk..., that is where that $10 comes into play. This is also the reason that some wholesalers get into trouble. This type of practice raises a red flag with the state because It clearly shows that you have no "intent and capacity to perform". This means that you clearly have no intention on purchasing this property if you couldn't find a cash buyer and if you can't find one then you're going to cancel the contract and leave the homeowner high and dry. It's this practice that gets wholesaling frowned upon. In my opinion, we as investors should always treat people with respect firstly... you wouldn't want someone giving you $10 for the purchase of your home so don't insult someone else with that amount. I would never do this especially if you want the seller to take you seriously and more so if you have to deal with a real estate agent for the seller. I've learned that good practice is a fair amount dependent upon the price of the property, but nothing lower than $500. If this scares you then you can always include a contingency clause with respect to that deposit, BUT you should always be wholesaling a property that you do in intend to purchase just in case you can't find a cash buyer. We shouldn't be wholesaling properties all willy nilly, if the numbers make sense to wholesale it then it is because it makes sense to flip/rent it. That is your exit strategy, investors should always have one that is good for them and the homeowner.
As to marketing the property, I would stay clear of that because you are blurring the lines of investor vs. realtor. Also in a situation that only involves a seller, you give an unscrupulous investor the opportunity to try and take the property out from under you when they approach the seller with a bigger deposit than you gave. Best practice is not to advertise a property you don't OWN. Its better to just advertise all the benefits that a cash buyer would be looking for and then leave your number. If it's a good deal then the cash buyer will call you and then you may disclose all other details to him over the phone call. You need to build up your cash buyer's list anyway; this is the perfect way to capture a lead I think.
Be kind and Smile!
