Web.config URL Rewrite specific match URL - url-rewriting

Question

I have the following web.config URL Rewrite rule:
<rule name="RedirectUserFriendlyURL1" stopProcessing="true">
<match url="^propertysearch\.asp$" />
<conditions>
<add input="{REQUEST_METHOD}" pattern="^POST$" negate="true" />
<add input="{QUERY_STRING}" pattern="^urlrewrite=([^=&]+)$" />
</conditions>
<action type="Redirect" url="{C:1}" appendQueryString="false" />
</rule>
<rule name="RewriteUserFriendlyURL1" stopProcessing="true">
<match url="^([^/]+)/?$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="propertysearch.asp?urlrewrite={R:1}" />
</rule>
The problem is it is applying this to everything so what I want to do is change the match url syntax to tell it to ONLY run when "-to-rent-in-" is included in the URL, so...
www.domain.com/villas-to-rent-in-florida
WILL qualify and have the rule applied, BUT this wouldn't
www.domain.com/testentry
I have tried different variants but it keeps hitting an error :(

To get the url to trigger the rewrite only when -to-rent-in- is part of the first portion of the url, you could use:
<rule name="RewriteUserFriendlyURL1" stopProcessing="true">
<match url="^(.+-to-rent-in-.+)/?$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="propertysearch.asp?urlrewrite={R:1}" />
</rule>
url="^(.+-to-rent-in-.+)/?$" will match any url containing at least one character before -to-rent-in- and at least one after.
You don't want to limit the character(s) before or after to be only alphanumeric since your url can be like: www.domain.com/apartments-to-rent-in-new-york (where new-york contains a -)
