Post-offer jitters - advice needed on condo value

[Account Closed]

I'm hoping that the good people of BP can help me come to my senses:

Just made an offer for a 2 bed 1 bath condo in Canton, MI. Offered full asking price of 154K. 

When I looked at the comps I was shocked to see that the listings that closed in the last few months have been leaping in the closing prices - in February high 130', Low 140's in the beginning of April, high 140's end of April. The last condo of the exact same floor plan closed about 2 weeks ago at 144. After speaking to the agent who is familiar with the local market (I am out of state) she recommended offering full asking price. Said that given how hot the market is all the seller needs to do is wait for 2 weeks and they'll get it, if not more.

I did go ahead and make the full price all-cash offer which will probably be accepted. But can't help getting jittery with this crazy market which keeps on leaping ahead at a crazy fast pace... What do you all say? Should I stick with it or pull out and try to negotiate?

PS this property would be a primary residence for me for about a year or so, after which I'm planning to likely rent it out. I do need a place to live there asap so getting a bit desperate however don't want to make bad emotional decisions, hence I'm here asking for advice :)
