My question is, should I have the brrrr under a different LLC? 

Happy to connect and answer any questions you have! 

I would start by watching this forum and doing searches for specific questions that you have - they've probably been answered a hundred times already. 

I'm a novice (like "I don't know what questions I need to ask" level novice).

The main factor in addressing your question is based on income so your qualifying income and that formula (46.99%front/56.99% back end) will determine your maximum borrowing power or ability.the front ratio of 46.99% is just the monthly PITIA(principal/interest/taxes/insurance/assessments) divided by your income.

Quick question for you based on where I’m at:I’m in Northeast PA with 3 duplexes, netting about $3,300/mo, around $300k+ equity, and about $50k cash saved.

Quote from @Anthony Nate: We talk a lot about rates, LTVs, leverage, and speed but the real question is this:What makes you immediately STOP working with a lender?

Quote from @Nathaniel Carter: Seeing more investors using DSCR loans lately, so I wanted to share a quick summary of why they’ve become so popular:Benefits:No income or employment verificationApproval is based on rental incomeClose in an LLC30-year fixed ratesWorks for long-term, short-term, and mid-term rentalsGreat for self-employed investorsGreat RatesThese loans have been helping a lot of investors scale faster, especially those who hit DTI limits with conventional lenders.If anyone has questions about DSCR structures, cash-out refi options, or how to qualify, feel free to drop them here — I’m happy to help. 

You are asking good questions that set you up well from both a cash flow and tax perspective.Here is how I would look at each piece.

@Barry FuchsThat is a very difficult question to answer not knowing your situation.
