Run "FindNext" only if button is clicked in userform - excel

Question

I'm setting up a userform to find a company's name. Each company has 10 rows of data. I need the button to select the first row and then stop and only run the findnext if button is clicked again.
Currently my code finds the company's name correctly, but because of the loop it directly select the last row with the company's name. I need it to select the first time the name appears and then findnext only if I click on the button again
Private Sub CommandButton1_Click()
Dim lastrow As Long, i As Long, c As String
Dim mycell As Range
lastrow = Sheets("Rent Roll").Range("A" & Rows.Count).End(xlUp).Row
c = TextBox1.Text
With Sheets("Rent Roll").Range("C5:C" & lastrow)
Set mycell = .Find(what:=c, LookIn:=xlValues)
If Not mycell Is Nothing Then
firstAddress = mycell.Address
Do
mycell.Select
Set mycell = .FindNext(mycell)
Loop While Not mycell Is Nothing And mycell.Address <> firstAddress
Else
MsgBox ("Not Found")
End If
End With
Exit Sub
End Sub
If I enter "Google", it should select the first row and then stop. Then if I click the button again, use findnext and select the next cell with "Google"

You should be able to to something like this:
Private Sub CommandButton1_Click()
Static lastCell As Range '<< static variables preserve values between calls
Static lastTerm As String
Dim ws As Worksheet, rngSrch As Range
Dim lastrow As Long, i As Long, c As String
Dim f As Range, afterCell As Range
Set ws = ThisWorkbook.Worksheets("Rent Roll")
Set rngSrch = ws.Range(ws.Range("C5"), ws.Cells(Rows.Count, "C").End(xlUp))
c = TextBox1.Text
'new search term?
If c <> lastTerm Then
Set lastCell = Nothing
lastTerm = c
End If
If Len(c) = 0 Then Exit Sub '<< nothing to search for
If lastCell Is Nothing Then
Set afterCell = Rng.Cells(Rng.Cells.Count)
Else
Set afterCell = lastCell
End If
Set f = rngSrch.Find(what:=c, after:=afterCell, LookIn:=xlValues)
If f Is Nothing Then
MsgBox ("'" & c & "' not found")
Else
If f.Row < lastCell.Row Then
MsgBox "Already at the last row" '<< do this, or just keep wrapping round?
Else
f.Select
Set lastCell = f
End If
End If
End Sub
