Success in creative financing comes from being a good communicator. I have done many many many creative financing deals from sub-2s, deed of trusts, land trust, lease options, and the list goes on.
0% interest loans I have done. Also, the complete opposite of that and have done interest only loans.
Now, all of that can be overwhelming, because there is a lot to learn. Make sure you study daily these different ways to purchase real estate. Eventually, you will land one, and then another, and then another, and next thing you know you are the next big guru. lol
If you want to catch a 0% interest loan. Here is "A" way. Notice, I did not say "THE" way.
If you are making a cash offer and the sellers think you are to low and they will not go any further lower than the price they are at, but they are serious about selling. Tell them "The only way I can do that price is if you finance it to me" If they ask, "what does that look like?"
*Grab calculator
Take what you want your payment to be... lets say you want your payment to be $400/month (Keep in mind you will be taking over taxes and insurance possibly- I am just giving you an example). Lets say that the seller wont go lower than $50,000 (random numbers so you can understand)
Take 50,000/400= 125months
I would say "I can make you payments of $400 for the next 125 months to pay off the $50,000"
If they say "yes" than you place that into your purchase and sales agreement right into the price section as such. Price:$50,000 with monthly payments of $400/month to be paid for 125 months. Your title company should be able to process the deed of trust or mortgage.
This is a 0% interest loan that you just nailed.
If they say "no" that is to long. I work balloon payments next (Next discussion... one step at a time here) or other types of offers to figure out something.
But for the most part, that is the main jist on how to get a 0% interest loan.
Hope this helps
