Properties that require minimal work are the first choice for rehabs.
The best opportunities for resale are houses that attract the most amount of buyers. That would be the price point for first-time home buyers in your local real estate market. Be cautious with expensive houses, because as the price goes up, you continue to limit the number of potential buyers who can afford it.
When a seller wants too much, offer to pay that price but use seller financing that makes sense for you. I always will pay full price or more if I can get a zero-percent interest loan.
Depending how a seller responds to terms, you can use that negotiation to lower the purchase price to an all-cash sale.
