Also there are weather issues with Indiana winters and pipes possibly freezing, thunderstorms and hail damage2) Knowing how long to hold onto a property, 1031 exchange it to another property or DST, or in some cases sell it and pay the small capital gains tax (if any) to have less headache. 3) Underwriting the deal incorrectly (factors: local appreciation, rate of rental increase, economic growth, gentrification of area) and being overly optimistic (a renovated 100 year old home is still going to have problems).

In which markets have you noticed particularly strong performance recently in terms of rental demand and occupancy rates?

A+ rated schools.

Seems like they are running a Pawn Shop, homeowners in Austin/Miami/Tampa etc who need cash bad sell a "HomeShare", percentage of their equity in their home for a discount, with a term of 10 yrs, if the homes go up in value as they have since 2011/2012 then NADA gets the original equity already at a premium price plus any appreciation for the total percentage they bought from the homeowner, but since Austin now down 20% in last 12 months and other hot home markets may also continue to fall, and NADA does not engage in price discovery (ie shopping for best value) as they want to obtain a "Market Value - ETF like" of the cities they invest in.

I did not know you can get so much discount with Giada.

At today's rates I'm not sure it would cashflow by the time you add taxes, insurance, r&m reserves, etc.The average rate today on a 30-Year fixed is 7.38%. 

I know that 3% rate is great but look at the bigger picture.

Our lake house for example, AirDNA had us 4x over what the rate should have been.

I'm sure you can find a REALTOR that will offer you a discount.

I don't recommend doing that, however if you just got the loan, chances are the interest rate is in the 7s, so they probably aren't going to be trying to call it in anytime soon!
