To flip or Rent?? East Memphis property

[Ben Parrish]

In June I purchased a house in East Memphis (Colonial Acres) for $77500.  I completed a full renovation of the property and am now all in for about $107,000.  I have a potential tenant that will sign a 2-year lease for $1500 a month and am in the process of doing a cash-out refinance.  However, I was recently given a cash offer for 170K with no contingencies. Originally I comped the property to be worth $150ARV. I feel this is a very strong offer, and am tempted to take it to have more capital to purchase more properties. What are your guys thoughts?  I guess a large part of me feels that we are going to have a pull back in prices sooner than later? But, timing the market is nearly impossible...  Appreciate any feedback.
