I am referring to the preferred return only here.

For reference, I plan to purchase a duplex and live in one of the units.

As part of my answer to your question, I would actually refer you to the part of David's book where he describes "Traditional Tom" and "Mastery Mike" (pgs 37-50 in the hard copy).

If you use their services, please let them know I referred you.  

I have several people I could refer to you for each of the positions you mentioned. 

Let them know you will be glad to give good references to prospective landlords and for them to reach out if they run into any problems.

Does anyone have any references?

For example, Google algorithms might decide that a business that's farther away from your location is more likely to have what you're looking for than a business that's closer, and therefore rank it higher in local results.RelevanceRelevance refers to how well a local listing matches what someone is searching for.

Me I can refer you to the one I use.

I’d love some suggestions on networking groups, as well as some references on lenders and realtors in the area.
