Every $100k in gain up to the limits, $250k (if single) or $500k (if married) will save you $15k in federal taxes and I’m guessing $5-10k in state taxes?  

These are Visio, LendingOne, @Timothy Hero as broker for a portfolio loan on 8 properties (if I remember the number of houses correctly) followed by a STR purchase, and I used Sortis for short term bridge financing on a property that was hit by hail while under the contract period so we had to switch to a different product until we fixed it up.

I own a few single family residence rentals, and I am in the process of transferring them to the LLC that I opened to hold my properties. 

I have owned single family section 8 rentals in the past, and while it was pretty straight forward, each jurisdiction likely has their own requirements and processes.In Cincinnati, again, I was buying properties on the MLS, they used to (maybe still do) use gosection8.com for LLs to list their properties.  

As of now, I've only invested in single-family homes in the Los Angeles, CA area.

If you are just holding the lot, then there are more favorable terms available than what you are currently experiencing.I always recommend shopping at least 3 different lenders (even more), as every single institution has different terms and requirements, and they all offer different financing products.

I went to all of the owners and was clear and honest with them about their current returns, expenses, ROI and potential future returns, every single one of them transitioned out of that investment class.

With a large property we think we can subdivide into four slender one acre lots and build 4 single family homes.  

I’m looking to scale up my portfolio this year by 1031 exchanging or plain selling my single unit portfolio for a multifamily 10+ units. 

If they are doing well, a good PM can make your life a lot easier and your investment more productive.
