I found a few cash buyers through a software and looked them up on internet to find their phone numbers.My question is how do i introduce myself on the call?

Decide on your cable/internet company, (have your agent ask if the seller can transfer the current service if it's one you like), if they won't transfer, call your favorite provider and ask if they service that address and set it up3.

Then low-cost computers and the Internet changed everything.

It is usually better to do that face-to-face rather than over the Internet. 

Anything you find for sale on the internet like Facebook, Craig’s list, etc is likely going to be garbage.

I would caution you on the two big companies I have funded a few folks that bought through them and they have all been poor properties for too much money..I can't think of a risker thing to do than out of state flipping for the smaller investor. you need to have someone on the ground that you know VERY well and trust.. and you are going to have a hard time finding that person on the internet or reading a book on how to do it.. theories are great .. reality is way different..

Internet AvailabilityHigh speed internet is available throughout most of Germany and Europe in General.

I understand the market is pretty competitive around here but we are optimistic we can find a niche and make this successful.I had my RE license years ago (before the internet!)

That should help the price of your dirt increase over time.For tenants, I like to look for things like services, restaurants or entertainment that are more 'internet resistant'.

An internet-connected device would be ideal, so I could monitor remotely.
