Core 4-BRRRR Edition

[Nicholas Creahan]

Hey all. I am buying a property in Cleveland area to BRRRR. I am in the initial phases of getting a cash offer accepted. I have a pretty good realtor and property manager. I have a decent contractor lined up, though I have not worked with him yet, people have recommended him and their reviews seem legit. Last bit, which I guess is my question. Should I have a lender lined up and pre approved before rehab OR wait until rehab is done or nearing done until I get one in place? I am new to BRRRR, so any insight would be much appreciated! Also, I have not asked my realtor if he recommends any lenders yet, but does anyone have a Ohio lender they recommend? Thank you to the moon and back for any answers to my questions!
