Great info and thread!
Yeah, you and Revelate seem to have hit the ceiling with tax liens on your reports. It seems that with well aged credit and scores that are groomed the highest you can achieve is 730-740.
I have tax liens on EQ and TU but my oldest account is only 3 years 3 months with an AAoA of 1 yrear 10 months. I also have 2 inquiries on EQ and TU from 9/14 that are still affecting my scores. The highest I can get my scores are around 705 to 715.
Look for the light at the end of the tunnel though. The tax lien fell off my EX report leaving me with a spotlessly clean EX report and my EX mortgage score jumped 100 points!
Starting Score: EQ 653 6/21/12
Current Score: EQ 817 3/10/20 - EX 820 3/13/20 - TU 825 3/03/20
