Flex Loan Modification option after forbearance questions

[James Boreno]

Hello I have a couple questions regarding a flex loan modification offered by a couple of my lenders on different investment properties. 

I'm currently in forbearance for a couple investment properties with different lenders, they've all given me an option of a flex loan modification, but I have a couple questions if I decide to go this route.

1- will it have a negative effect on my credit?
2- will it cause hurdles in borrowing future loans? (I want to get a loan on a property in May)
3- will it cause hurdles in future refinancing other property loans?
4- will it negatively effect getting non conventional loans? (I will most likely get a bank statement loan for the property in May)
