@Mike Sattem  I personally wouldn't spend $8000 on the windows unless it either added value to the property as a whole, or increased the amount I could charge rent.

I decided to charge rents by the week, but with a 6 month lease. 

I've used a dog tracker -- a wireless, battery operated GPS devise which sends me a text message when the 'dog' stove, or whatever runs away.  

For example, ok to have family living with you for free or helping out with mortgage payments, but not ok to charge rent to roommates. 

Two, in a power failure a traditional landline (not VOIP) will still be operational since the telco uses batteries.

When I encourage people in any way it recharges my positive mindset batteries!!!!!!!

This is what you can do if late fee is not allowed:Say if you charge rent $1300/mo then write up your lease for $1450 and give 150/ discount if they pay by the 4th.

It has a built in battery backup, so you are covered for short periods of power outage or thieves unplugging it.

Up until then, we'd been running battery-powered tools... it was well-timed, as our last battery went dead shortly before the power company hooked us up.We also have water unlocked and ready to rumble.Got our HVAC guy out, as well as the roofer.

Now I just make sure it's in lease that they know they're responsible for light bulbs and batteries (amazed at how many think I'm coming over to change a light bulb for them due to prior apartment living.)
