I understand the mortgage rates are lower for second home compared to investment property.If I decide to rent this property in the future for any reasons (airbnb or leased), is that illegal?

The reason for NNN is I don't want to spend anything for maintenance/taxes or any sort of expenses.

I like to make more reasonable offers and negotiate credits during the inspection phase. 

If it isn't true, that's an even more compelling reason to address the issue.

Obviously you need to respect your tenant and their space, but it's your responsibility to maintain the property for a number of reasons.

The best place to begin is to purchase a course in how to invest in real estate, for the very reason you asked; "Where do I begin?'" 

Looking for a reasonably priced contractor in Stockton area in CA.

@Eric Patrick Oden, that approach works however the difficulty lies in selling 30 POH for $10,000 cash (or even $5,000) to potential tenants in a reasonable amount of time.

What is the reason for the Lease and Option?

I believe we have a long way to go to catch up in terms of both student rental housing prices and student rent rates (some students are still paying $200/bedroom).For these reasons, I believe investors can make a bigger profit with less risk investing here in Windsor.
