No eviction protection so since you gave to settle on someone with and low 600s credit score if you have to go to court they get to charge for their time on that. 

If their credit history is sufficiently long to generate a reasonable score for them then the credit score tells you the answer! 

If you want me to give you a quote, I'd need to know the address, 1st lien details (type of loan, balance, interest rate), credit score, income/DTI details, and target LTV (can go up to 80% CLTV on the 4plex). 

Start working on your credit score and research financing options, including FHA or conventional loans.

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

I stand corrected:)They do have an office in Metro Detroit and while we're far from perfect, we seem to get a lot of their unhappy previous clients.In our opinion, they built a system for Class A rentals - where tenants have 680+ credit scores and rarely have to be evicted or trash properties.They then tried to apply their processes to Class B & C rentals and that's when their service issues increased.All this caused them to recently significantly increase their Flat Fee pricing and monthly minimum charges.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

First of all I put my acceptance criteria clearly in the ad: minimum credit score (enter X amount, 620 is what I use),income 2-3x rent, good rental history, references, no evictions, acceptance dependent upon background check and employment verification, pet policy, desired lease term, etc. so that people will hopefully read that and not come to the open house if they know they won’t qualify.

Focus on getting your finances back on track first—start saving and work on building your credit score.

A HELOC carries a higher rate over a shorter amortization usually 10 or 15 years and a mortgage carries a lower rate over a 30 year amortization offering a lower payment.You have to run the math in each scenario because the math differs based on a few things like Fico score, CLTV, Loan size, and time frame between purchase and refinance of new property.
