As usual in most responses in this forum you are getting conflicting information. 

Most out-of-state investors looking at Detroit are typically focused on cash flow, which means they're usually targeting C or C+ neighborhoods.

I can quote from over 100 lenders instantly, but usually only work with fewer than 30 in a given year.

Weekends for a lot of people are usually tied up with kids sports, family functions and trips.

In our still relatively limited experience, seller financiers are usually looking to get a higher asking price in exchange for the favor of the private loan. 

I usually try to get 10k but sometimes its not possible and I would prefer to make something and give the investor a good deal rather than make nothing trying to move a bad deal.

I know they have a cap at 10.We have also looked at using local banks in the area but those terms are usually 3 years arms to ten year arms and 20 year loans so it lowers cash flow significantly. 

Unfortunately cap ex usually catches up to them and the appraised value rarely translates to a similar sale experience and all along the property has merely been a highly levered property.

My initial reaction was "hell no".Algorithms are usually poor estimators of actual value.  

This is usually a 12 month commitment that is "Interest Only" and after you finish the rehab and get a tenant, then you refinance into a DSCR loan.
