Would you accept this seller financing offer?? Need advice

[Stuart Dean]

I purchased a property in Feb2017 for 360k. Put about 15k into it. Property cash flows about $500/month. A lot of development is going on around the property, so my agent suggested a month ago to put it on the market for 499k and see if anyone bites. I am a buy and hold and was not interested in selling, but if someone wants to pay me that much sure I guess.

Got an offer today for 412,500 with seller financing. Here are the terms:

$412,500

10% down

5% 30yr amort, 5 yr balloon

FIrst time dealing with seller financing, so would appreciate any insight. Thanks
