Some ultra high net worth investors will float hundreds of millions in a portfolio in the 3's for rate.

*Summary* Don't use all your money for 1 DP on 1 deal and make sure that u have extra money for all costs for every deal so you keep urself floating after each deal.

Perhaps you can float that by your realtor, as they may be more likely to write your offers for you.

You're left with 2 days floating in between these stays that, because of your 3-day minimum, will not even be seen by anyone searching.

They just happened to be ~4.5% for 10 years (at the time my banks were 4.75% for 5 years, but now my local banks are 4.25% for 5 years then 5 year floating after).Why are you looking specifically for non recourse? 

However an idea that has been floated around has been using this as an opportunity to get into the real estate business flipping homes.

If you are going into the business you will need the ability to float expenses for months.

But if I do you are missing the cost of the loan unless this hypothetical seller is floating you at 0% if not over 30 years your 90k loan comes to 64k in interest payments at current rates.

-- If the worst case happened and it just didn't rent, would floating the expenses for this property change your quality of life in any way (For example, would paying your mortgage, buying food/clothes, etc be affected)?

For performing notes I would keep the term short if you have a floating rate HELOC.
