I guess it's all dependent on how much equity you can provide to a house during the rehab portion of the BRRRR method. 

I'm one of the owners of JWB and would like to provide some additional information as well as clear up any miscommunications.

Private money lenders or construction loan specialists, on the other hand, are faster and more flexible, though their rates and terms will likely be less favorableFor a more rural area, local banks will almost certainly understand the market better, but connecting with private lenders who specialize in spec homes could provide more agility.

And, when there is a vacancy, can the remaining units provide enough cash flow to cover all costs?

A primary residence will most often provide more favorable loan terms so if you are willing to wait one year while you living in your new property and are comfortable with renting out your primary residence to a tenant, then getting something such as an FHA loan is a good strategy to minimize your upfront costs and hopefully get better loan terms.

The lender is the one who sets this up as they are the ones who typically pay since its them who is to provide this as well as keep track of the loan, but only be a borrower if they use a servicer.

I've always believed in the saying that "there is nothing wrong with any deal, as long as the price is right" lol.This might sound cliche but all of Cleveland can cashflow if you buy cheap enough and if you buy with cash.And cashflow it can very well.Just like all of Ohio.You make money when you buy and not when you sell.So make sure to buy dirt cheap.Buying cheap also "acts" as a margin of safety for any mishaps that happen during rehab or issues like the OP had with the first property manager.I see many folks nowadays buying off the MLS and overpaying, spending too much on rehab and then getting dimed to death by property management.While I'm sitting on the sidelines as a turnkey provider watching it all un-fold and thinking how they just could have bought my "overpriced" turnkey property and would have been into the deal for at least 30% cheaper...It's a shame but it's what the people want, so many give the people what they want.Thanks 

I do have a pool company coming out to provide estimates. 

We use Propstream but I am looking for some added info that Propstream does not easily provide  @Sean OToole is the owner and he has built an incredible platform..

@Kevin M Dobyns-Do they provide commercial loans for rentals or buy to live for a certain amount of time then list it as rental?
