Many things go into determining value such as location, condition, quality, schools, modern (open floor plans), size of lot, etc. 

Having positive and motivated people around you is the biggest "hack" that is often overlooked.

Hi Mike,Purchasing a 2nd position lien only gives you the note holder the rights to collect payments per the note and mortgage for that specific lien.

You should consult the laws regarding interest rates before putting yourself in a bad position?

Just wondering about vacancy, quality of tenant, etc.

If you purchase less than your sale or if you take cash out from the 1031 you will pay tax on it as profit.However, If  you want to accurately calculate your tax position in a property you must calculate the adjusted cost basis.  

It will depend on what you qualify for and the quality of each of the properties, if quality is the same and you qualify for enough a fourplex would obviously be better

Then if there was a field for estimated tax bracket or whatever, the calculator should be able to account for the taxes on what is left of positive rental income if expenses don't account for it all.

Cali and am looking to buy a vacation rental that is cash flow positive but a place we could occasionally use as a vacation home.

We do have properties that have achieved the infinite return over a longer duration (due to market appreciation).Congrats on a great purchases, being in a financial position to pull it off, and putting yourself in position to pull it off.
