Someone with no debt will have a different calculus than a person with high credit card debt, and so on.Ditto @Greg Scott, @Clancy Catelli, and @Thomas S., and @Ray Lai

A good example would be trying to tackle calculus before you did Alegbra.

Currently, I have been living in the Lisbon area (Cascais) for about 2.5 years.After some investigation into the Portuguese Real Estate market we (my wife and I) decided that with Portugal’s rapidly growing tourist influx that the risk/reward calculus pointed to STR.

Here’s my current calculus in my area of New Jersey NJ - each 1 furnished room rents for $1000-1200/mo with like 5% vacancy and each furnished 2 bedroom apartment rents for $2500-3000/mo with 10-15% vacancy.

It becomes a calculus exercise. the extra thousand raises seller costs, but should cover the extra costs at the margin in most instances. 

My mental calculus is that I want returns in excess of 25% above what the passive S&P 500 Index has returned historically (~8%).  

As a lender, I'm sure you know a million agents, but you may consider finding one who owns investments, and therefore understands not only the mathematical calculus of divesting from an investment, but the emotional ramifications as well. 

This reminds us of a 2nd grade math teacher taking all the credit for his student getting an A in calculus.

Gotcha...The calculus of that decision is different if you are investing from overseas.

Finally, in the event of default, as we work through the grace period we could get the deed recorded in our name before we sought a new buyer (if we couldn’t get the current buyer back on track).Obviously I’m getting the sense no one here’s a fan of skipping recording, I’m just wondering if these additional aspects change the calculus for you at all.
