I am also researching lot of these aspect.

Being curious and accepting that you don't know everything is one of the most important and freeing aspects of investing. 

I'll be happy to help you with the financing aspect of your investments. 

Since your goal is to build a portfolio of rental properties, you’re right to weigh both the financial and practical aspects of this decision.

The appealing aspect here is the ongoing population growth and other economic factors.

I'm just not familiar with the flipping aspect of homes this age and just want to be cautious going in.Thanks in advance! 

As for the refinance aspect, if you're going from LLC to individual (or vice versa), at my shop you would just transfer title into (or out of) your LLC at the close of escrow, so that part is no biggie.

For you, is having a 5-star overall rating on rental sites the most crucial factor for success, or are there other aspects that you consider even more important?

So you want both aspects. 

Now with essentially free money being gone, not only in BRRR is it more challenging but every aspect of real estate is more challenging and we are going to see a lot of people lose a lot because of inexperience of not knowing their riskI totally agree, thanks for the input!
