Screening tenants was very different then-no Internet.

First, if you are picking markets that are called hot in forums and on the Internet, you are too late to make money there, especially long-distance wholesaling.

Renovating a house 1200 sqft. Opinions on making it a nice 3 bedroom with master bath and walk in closet or 4 bedroom with just to baths no walk ins. Plan is for a hold rental?

I've poked around the internet extensively looking for a calculator I like but haven't found the perfect one.

You might see if cable TV/internet is available.You might check if Natural Gas service is available by calling that utility unless you know Propane or all-electric is the norm in that area.These are the first steps in my area. 

Really depends on layout of house and locations of utilities. 

However, the layout of this house does not allow for an extra bedroom.

You will start to see the neighborhoods, what you like or don't like (you cannot get this from the internet pictures and street view).

I don’t have any other bills besides electric and internet.

But then now your talking big money. 3k for a decent stacked machine. 500 for the card reader setup. 40 bucks per month on internet service for the card readers.
