Unlike traditional banks, which focus heavily on personal credit and income, portfolio lenders prioritize the cash flow of your property.

I never really know ahead of time which lender might be open to that before putting the full credit package in front of them, and many of them 'in theory' offer it, it's just a matter of exposing the potential transaction to enough credit unions and banks that a few "swipe left," a few "swipe right," and looking at the terms offered by those that swiped right.

I did this in the MS market and while the advantages you pointed out were true.. markets that have slow appreciation and or areas where builders can keep building for low dollar amounts like the mid west.

For me A or B grade means that you can get a tenant with a 700 plus credit score with an income well above the minimum threshold. 

Plus funding is readily available and deals need to mature a few years before profits emerge, so why would a turn key provider not just keep a good rental property.Our inventory is so low in Milwaukee, that sellers don't have a reason to give a discount. 

Screening tenants well and then a security deposit or credit card hold process in place will limit liability.

Have the tenant pay for repairs and maintenance with future rent increases by using a line of credit.

I moved from the SF Bay Area to live and invest in Reno, NV because of it being much more landlord friendly, low property taxes, close to Northern CA and Lake Tahoe, strong appreciation, and I understood the market after speaking to a bunch of people and feeling confident about the future here.  

If you want to fill your property with residents sourced from the companies above, imagine being the overworked, relatively low-level employee tasked with finding the appropriate housing ASAP.

We had to pay the utilities directly to Baltimore City to stop the late fees from piling and have our credit affected.Maverick, on the other hand, continued to advise us to be patient.
