With lab fees, low reimbursements, interest? Do you think still a good time to open a practice?

I've just come to an opportunity to buy a practice from an owner I used to work for a while ago, this one has been closed for a while, and he is ready to let it go. Basically I'll be doing a start up, the banks hate these kind of situations to finance so owner probably will finance, and I'll get lawyers + brokers involved, but wondering if it's even worthy to do so? I don't know how much would such an office be worthy. I think making an assessment on the equipment would be a good starting point for price right?
