Does anyone know of any references or websites

No tenant/contractor images or "video tours" - boots on the ground with eyeballs!  

Has anyone used services like "Archinerds", "Southern Athena", etc. who advertise that they specialize in helping navigate codes and permits and refer you to building/remodeling professionals?

I know some great contractors I can refer if needed depending on the project!

Key things to look for:(1) Experience - however much you deem acceptable(2) References - contact the last 3 customers they did similar work for(3) Compliance - be sure they're following local rules in regards to permitting/inspections (4) Specialty - a lot of guys say they do it all.

Most maintenance problems are resolved within minutes, a few hours, or even a few days and the more you handle at one property the less you have to travel to properties with less units.We often go to our 60-unit building and 5 to 10 tenants come of of their apartments to tell us about maintenance issues, but don't forget that you make great profits from every one of those tenants.I put in two images showing approximate profits for a 20 unit building if you raise the rents only $30 to $40 per year.

Any insights, thoughts, ideas, or advice always welcome as well.130 Woodlawn Dr **(link to listing above for reference/non promotional purposes only)I ran an Airdna report for the address to give an understanding of the local market, but would love to hear insights on pricing given the uniqueness and potential market opportunity. 

Were closing on one Thursday, I'll throw my numbers and reasons out there for reference.

Paper currency got its start as little promissory notes to pay gold, and then because the notes were more portable than gold, people started using the notes as money instead of the gold itself, which is why you sometimes see references to "one dollar notes", etc.A seller may or may not accept a promissory note as payment. 

Make sure they are clean and actually call their references.
