Although the included features are basic the homes are more energy efficient than older homes, simple due to the changes in building code updates, over the years.The homes are mostly brick, the siding is made of HardiePlank, and the windows are double pane vinyl.

If the main panel is split into two primary circuits and each of the two circuits serves a sub-panel in each apartment, then you could have an electrician install a eamon demon sub-meter on each line that is serving the sub-panels. 

Firing a father -in-law is going to strain your relationship with him, and in the long run, strain your relationship with your wife. 

When the right tenant comes along, I lower the rent and tell them it is because they are exactly the kind of tenant I am looking for and how hard it is to get good tenants such as themselves.If I don't want to rent to them, I give them the application and send them on their way.Later on down the road, when the relationship gets strained, for whatever reason, I remind them that I chose them because I liked them.

I found I could get new glass panes 1/4 of what they want here by shopping in north Texas.

We did quick inexpensive fixes and rented to a low income person who applied for weatherization and the program put in new double pane windows, a new cooling system and insulated the attic. 

Then it probably would be a big plus to redo the plumbing.100 amp if it is breakers would probably be ok, if the panel is big enough for all of the circuits you want to add. 

Make sure your electrical panel is properly grounded.

In my opinion if they signed a lease and gave deposit to hold the property and it is clear in writing what the next steps are and they do not perform per the agreement then they have violated the contract and forfeit the security deposit because that is what was holding the property and you could have leased it to someone else so technically you could be out potential money.Now the flipside to this is you may be right all day long, but if they sue you over this you have to get legal counsel to defend yourself and deal with the headache and mental strain of battling this, probably spending way more then if you just gave them back the money and moved on.

As the younger, less experienced person, I offered less profit for myself in order to use his capital and build my portfolio while doing so.The one thing to be cognizant of is working with family can put a strain on the relationship.
