Great feed!!! Love the info.
@Michael Clevenger, I would just like to add a little more "down-the-road" on @Brandon Ingegneri's recommendation. It's a great strategy. I agree. It's essential that you know, however, that SHOULD your buyers default on their payments to the 1st lender (you are the 2nd) then in order for you to protect what's remaining owing to you on your note ($50K in this example - the payments they make before defaulting = $45K, for example) ... so in order for you to protect your money, what's owing to you, you will need to keep the 1st mortgage paid up and then YOU will need to foreclose on the owners/currently buyers.
It's a great option for now ... just please know what the future can hold and have a strategy in place for that.
And if they're not paying their 1st mortgagee it could be that they're not paying the realty taxes and maybe they've let their insurance lapse. I worked in law firms for 1/4-century, where I was the real estate specialist, and this happens more frequently than not. It can still be a good deal for you, though. KNOWLEDGE is POWERFUL. :-)
