In most cases, I don't recommend renting out your primary residence especially if you have no rental experience and that is because usually your primary residence was bought without the idea of renting it out.  

3: I have no idea how to determine how much to borrow verses pay cash?

I know there is no one right answer and some variable, but looking for ideas/advice. 

This thread shows there is a need for a larger guided discussion on best practices as it relates to (renters) insurance.

Luckily I am not easily sold on any ideas without some data to back the ideas.

One good idea is to connect with the social worker department at the hospital to see if you can assist with anyone traveling to the area. 

The hang up is getting deals formally drawn up.One idea:- I buy the property and pay 25% DP, then they provide capital after the closing and I pay them P&I over 5-10 years.

Selling it now seems to be not a good idea as I will lose 50% of my capital.

They moved in and within 24 hours sent the following letter (names have been changed): "Hi Dawn and Brian,Sindy and I are frustrated, disappointed, and really struggling with the idea of moving forward with the move into your home.We realize this is the first time you have rented a property to someone, and may not be aware of the responsibilities that landlords have, and want to inform you that there are habitability issues with the home that are quite literally against the law, pursuant to Colorado’s Warranty of Habitability Law, CRS §§ 38-12-501 et seq.

I guess to get a definite answer I'll have to cold call to get see if all these people are behind on their payment or it's just a standard practice behind some salesmen!
