Whether it is profitable depends on the cost of electricity from your utility; your local/state incentives and net metering policies; and the cost to install the solar panels.A pretty easy and quick way to run ROI on a solar system is to use this tool put out by Google: https://sunroof.withgoogle.com/If you look at my post history, I'm in a similar situation and I will be going forward with solar when I do my roof.

For the new construction: In my case I have to buy a separate sewer line (which is not metered - just flat fee).

I'll be extending city water and sewer a few hundred feet up the highway and metering spaces separately.

To illustrate the seriousness of the situation, consider this example: an apartment on Calle Princesa in Madrid, a premium area, valued at 450,000 euros and 70 square meters, will be legally required to rent for a maximum of 950 euros per month.

He ran out of funds and was not able to pay the electric company to hook up the meter.  

We put an emphasis on vacant prospects, those with separate meters and realistic balance sheets which when combined with the right financing terms and management can still produce a healthy and safe addition or anchor to a portfolio. 

There are two separate electric meters on the property with a well for water.

You can buy a cheap moisture meter to check walls to see if there is any moisture. 

Before you submit an offer I would also make sure you know all the additional expenses that you may me overlooking, is it separate metered for water gas and electricity.

Joe that is the way its suppose to work and exactly how we did our sub toos  as you point out though when this technique starts to get marketed to the NO money no Credit RE crowd its going to cause some severe headaches for Sellers and Buyers.you hit the nail on the head of Chris's situation I am guessing and if I was buying paper like his fund does I would do EXCATLY what he is doing buy discount have the right to accelerate and get cashed out spins the APR meter dramatically for an investor or a fund.
