The internet is dangerous for research but this article helped me.  

I starting scouring the internet and bigger institutions and it seems the lenders doing HELOCs on investment properties has dwindled. 

Since this is a cruise, I won't have access to my cell phone and limited internet access(I get 30 minutes free for the trip and can pay for more as necessary).

I have been out of town and I did not realize I would be without internet service.

@Valentina Woodson, I would try to find their phone or email via the Internet, social media sites, etc and if you do not have luck pay $10-$20 for a skip trace.

I trade Futures online and the most important thing for my Residence is to have a fast internet connection for my Daily Cash Flow from my trading.

For title insurance, call the closing attorneyMortgage payments-This is not fixed, it is variable, there are lots of calculators on the internet such as http://www.quickenloans.com/mortgage-calculatorProperty taxes- Also varies per property, look up the assessed value on each property via a link from the town website, and then the town tax rate should be listed on the town website. 

if so (and you probably should), it should be factored into your numbersi can't estimate the rent without knowing the address or cross streets, but i'm sure the combination of your property mgr/agent/internet can help confirm. hope this helps, and good job!
