Friday is the deadline for offers to buy the Tynecastle club, who entered administration last month with debts totalling £25m.
This has led to them being handed a 15-point deduction and put under a registration embargo.
Edinburgh businessman Bob Jamieson and USA-based company Club 9 Sports are both expected to make bids for the club along with supporters group, Foundation of Hearts.
Locke's only concern, though, is the ongoing health of the club.
"I don't have a preferred bidder," he said. "I just want someone to come in and, first and foremost, have the club at heart and run it like it should be run. If I get that, I will be more than happy.
"Whoever comes in, we are just looking for Hearts to get back to where they should be, being a top club in Scotland and trying to get into Europe and challenging for cups.
"We don't want to see ourselves in this position again."
However, the 38-year-old does not expect a quick resolution to the crisis at the club.
"It would be great for us all but speaking to (administrators) Trevor (Birch) and Bryan (Jackson), I don't think it will be done overnight," he said.
"I think it is a bit of a drawn out process but obviously for myself it would be great if it was done quickly and I had an opportunity to bring in a couple of players before the (transfer) window shuts.
"But if that is not the case, we have to get on with the players we have and do our best."
It has been reported that the United States-based consortium will seek to move the club from Tynecastle to a new stadium.
"It's not something I have thought about," added Locke. "We are back on the
training pitch and that is the only thing that concerns me.
"If a new owner comes in and wants to move away from Tynecastle, that's up to them, it's not a question I feel I need to answer.
"At the moment, we are just happy to be here, happy to be surviving.
"You could possibly see the benefits when you look at some of the big clubs
who have moved stadiums down south but Tynecastle is our home, it is where
everyone associates Heart of Midlothian and it is a fantastic arena in which to

is certainly no different for me."
