Personally, I think I would stack some cash for a year or so while I did this. 

Of course most GPs have personally put in money to keep the deals from sinking.

I heard that if you move the personal mortgages to an LLC they could get called and we would want to avoid that3.

Quote from @John Friendas: As a person with an average salary, I was wondering what the maximum amount of DSCR loans a lender would give out would look like?

I’m not convinced it makes a real difference unless a person has a unique setting.

Or a personal loan if interest rates aren't cost prohibitive?

Try being an agent, your phone number is EVERYWHERE and you get targeted by a whole industry that wants to sell you the latest gimmick.Here is what helped me.I answer calls and when it's a telemarketer I will interrupt them and say very friendly (because I don't hate the poor person who gets paid to do this and coached to be ruthless): Hey, so glad you called, can you do me a big favor? 

While this job could be performed remotely, working with my peers in person for at least a year is important to me.

I don't know if they still do it but if memory serves a few years ago TD Bank would do a HELOC on a rental in second position but only if it was titled in someone's personal name. 

My recommendation would be to engage an investment property focused realtor (not a general residential realtor) and let that person guide you through the process from pre-qualification to market/property valuation and selection.
