There are also people who swear by one method or another.   

Also, it often helps to connect with a local agent/do extensive due diligence on renovated/new construction properties to see what the property may sell for or appraise for (if doing BRRRR method) as that can impact the price you should pay.

You definitely want to use a thorough screening method like rentprep.com that gets their income, credit, background check, and call at least 3 references (make sure to verify them by address/job and then their name).  

My borrower is refinancing the loan to hold the property (BRRRR) and I'm wondering if the new lender will have any concerns with this policy. 

I use their payment method and they deposit into my account and it's very simple.

I’ve been investing there since 2019 and built a 12-door portfolio using the BRRRR strategy.

I hope to find a single-family home with at least 4 bedrooms, use the BRRR method to turn it into a short-term rental property.

He uses poorly thought through methods, I've listened to his "methods",  Thus, he has the high amount of  Due On Sale called in a short period of time. 

@Chris Morris have ALWAYS seen bad "deals" from rookie wholesalers that really don't understand what they are doing to provide value to the industry.It's getting worse because the real estate market has recovered from the 2010 Crash, yet many are still using tactics & methods developed during this time.Everyone in the industry needs to go back and look at what was being done BEFORE 2010 and start using those methods, updating them with current technology.

This means no DTI, personal income verification, or tax returns are required.They’re also becoming a powerful tool for BRRRR investors during the refinance stage.
