Actually building a replacement property would be a problem due to the time requirements though.

When the mortgage is actually paid off, the deed and completed note are probably most important.

Because there is no flex in this period after day 45 we always highly recommend that you actually get your new properties under contract during the 45 day period to mitigate risk. 

Early on, I thought that as I collected actual performance data in my portfolio, I would be able to pick one over the other in 3 to 5 years.

I've actually done a lot of that in the past, and achieved much success.

Whatever you may absorb while going to class and studying for your test, will not be part of actual the "real life" transaction..  

@Sam LaGrassa @Aaron Hunt  The actual market numbers for Suffolk County, MA for Q1 2018 vs Q1 2017:Median home price: UP 15.9%Average home price: UP 14.4%# of homes for sale: DOWN 33.5%Days on market: DOWN 6.5%Months supply: DOWN 29.7%  (1.2 months)Now that's not to say that those numbers will continue, but that is the actual historical data for last year.There's still an incredible shortage of homes on the market. 

A lot easier to find the court order.....if it actually happened it’s in a court file somewhere and shouldn’t be too hard to track down with the parties names and a general timeline, then record it.

@Joshua Horn Actually there's a 3rd way too.You can get an Option to Purchase and file it on title.

That actually helps a lot!
