I would be willing to lay the ground work and producing the Yellow Letters.

Make sure you buffet for the taxes resettingI’d only be attracted to these numbers if it was a “set it and forget it” type of property with good resale value.

I'm currently involved in some HoA litigation about improper reserve funds, and I can tell you that this area of law is very muddy and attracts stubborn people. 

They are targeting business travelers / professionals (it's their first time doing this, so who the ideal market is for them is up for debate - but the idea is to attract quiet people who can afford it).  

Same everywhere, any listing priced well below market is likely going to attract multiple buyers offering over ask price.

If you consume less than your system produces, your credit from the utility can offset that amount too.If you think of a rooftop solar system as a "fuel tank".

The part that was attractive to me about this loan is that you can still do an fha purchase down the road and secure another property with a loan downpayment.

With the market where it's at, with so many people overpaying and thus driving prices up and making deals assets less lucrative, this structure allows deals to still be attractive for upside investors while providing a nice safe (in some cases, not all deals are safe/good) investment for those who are looking for capital preservation over growth.

The more bids any property gets, the less likely financing will be attractive unless it is much higher.

However, most lenders will only allow HELOCs up to 70% LTV on investment properties (as opposed to 90-95% on primary residences), and the rates aren't as attractive, whereas you can get 30-yr fixed loans up to 80% LTV on investment properties.Curious why you are going for HELOCs as opposed to fixed mortgages?
