New Investor - BRRRR Nuances

[Brendan Hula]

Hello BiggerPockets Community,

I'm a new investor, although I've worked in institutional commercial real estate for a number of years in the Asset Mgmt & Development groups at a few large REITs. 

I'm currently reading Brandon Turner's "The Book on Rental Property Investing" and had a few clarifying questions on the BRRRR strategy described in the book that I was hoping the community could help with. I would appreciate any input or advice the group has on some or all of the questions below related to the BRRRR strategy: 

-How likely is a bank / traditional lender to refinance a property if it's owned by an LLC? Assume the property is a 2 to 4 unit that was purchased for cash, has been renovated, is fully rented, and asking for a 70% LTV. I'm wondering if the LLC ownership would be a non-starter for a traditional lender, even if the property is fully rented and cash flowing.

-If a property is purchased via cash and renovated, is there a seasoning period (ex. 6 months) before a lender would agree to finance / lend on the property?

-What strategies have been successful for individuals in terms of lining up traditional lenders to agree to refinance the property post rehab and rental, prior to the initial purchase? Basically, have you been able to line up refinancing down the road prior to making the initial purchase and undertaking the rehab?  

-Any advice or helpful tips for coming up with a realistic after-rehab value (ARV) and an accurate rehab budget that's necessary to drive the expected ARV?

-Lastly, if you purchase a 2-4 unit multifamily, for the refinance will the traditional lender base the valuation on the NOI / Cap Rate, as you would for traditional commercial property, or will their valuation be based on comps in the market, similar to residential / single-family properties?

I know this is a lot so appreciate any help / guidance the community is able to provide. Thank you!
