For flipping... generally people target either a set profit amount and subtract it from their ARV with carrying costs, purchase price, and rehab costs to come up with a max budget... other people do 70% of ARV minus rehab costs as a target.For rentals, it depends if you're an appreciation player or a cash player (CoC returns rule here). 

Maybe attend a local REIA Club as an "Investor" and get to know some of the players in your region before you expose the Money Lender hat.Call other Private Money Lenders and pick their brains local to your region...they usually don't have any problems sharing their experiences with you.Attend some Auctions to see who is playing in that sandbox, collect business cards and begin your due diligence.When you're ready, reach out to those that you pre-vetted above. 

Its why the MULTI players all look at higher rents lower cap rate drive significant appreciation which is what they are looking for.

Quote from @Brandon Peery: @Remington Lyman @Joshua JanusJosh I know Josh,( and 99% of the " players " in town )  he will agree with my assessment 70k MAX, this is not a good area with low rent. 

I feel too many people get caught up in the A and B class properties and it's mostly institutional players in that space.
