Sell or Rent My Started Home?

[RJ Staats]

We recently refinanced at 15 years on our started home that we purchased in 2014.  I GC'd it and handled most of the grunt work. Spent $100K over the years on top of the $380K purchase price. Market Value is $550ish but my refi- appraisal was only $500K.  We rolled 60K of debt in (cars & student loans) , took some cash and are just 2m months in on 15 year a 2.375. Monthly payment is $3450.00 ( incl. NJ prop taxes).   We owe basically 400K on the house and gain $1,200 in principal each month and have zero other debt.

How would I compare the benefit of selling now at various prices  vs renting at market ( which is $3,000-3,500 range) ?  

How can I find someone who needs creative financing...find a Lease Option Buyer for my house? is this a good idea?
