@James Hamling,
Thanks for providing an excellent definition of a portfolio lender for those reading. This would have been exactly how I would have defined it as well.
At this point in my investing journey, I have never needed / seen the point to deal with a portfolio lender, especially since I was able to get conforming loans for all my fourplexes as they were purchased in the $800k to $1.1M range, so easily stayed under the limits and I could get Freddie/Fannie money for 2.5% to 3%. When I did speak with a local portfolio lender, they wanted at least 4.5% to lend. They wanted me to "refinance" my portfolio, or some part of that portfolio into that higher rate with a shorter amortization schedule (25 years). That did not make financial sense.
Since this purchase is for a primary residence, there is no need for me to seek a portfolio or commercial loan, so I shopped around with multiple mortgage brokers in my network and provided a bit of education to the one who was providing the best quotes.
I have three fourplexes being built and for those I will get commercial loans with local banks. My current main bank isn't thrilled with financing out of state, but will probably do it because of our existing relationship. They will keep the loans and won't be looking to resell them. Technically the loans will probably be DSCR loans for two of them and since I'm partnering with a buddy on one of the three, he will get Freddie/Fannie money.
Still, I'd LOVE to have a referral, for a portfolio lender, who can do better than what I'm getting quoted from Chase and Key Bank.
