Regex Expression to extract Address Street from a string

Question

Given the sample texts, I want to extract Address Street (text between asterisk). Using the below Regex Expression, I'm able to extract Address Street for most of the sentences but mainly failing for text4 & text5.

regex = r"(^[0-9]+[\s\-0-9,A-Za-z]+)"
text1 = *9635 E COUNTY ROAD, 1000 N*.
text2 = *8032 LIBERTY RD S*.
text3 = *2915 PENNSYLVANIA AVENUE*  40 Other income (loss) 15 Alternative minimum tax (AMT) ilems
A 2,321
text4 = *2241 Western Ave*. 10 Other income loss 15 — Altemative minimum tax AMT itams
text5 = *450 7TH STREET, APT 2-M*
text6 = *9635 East County Road 1000 North*

My code---
for k,v in val.items():
 if k == "Shareholder Address Street":
   text = " ".join(v)
   pattern1 = r"(^[0-9]+[\s\-0-9,A-Za-z]+)"
   addressRegex = re.compile(pattern1)
   match = addressRegex.search(text)
   if match is not None:
      delta = []
      delta.append("".join(match.group(0)))
      val[k] = delta

Can anyone please suggest the change in the above regex as it is working fine for most of the documents?

Use

^\d+(?:[ \t][\w,-]+)*

See proof
