If so, should I be thinking about get rid of the property right away before the construction starts?

Have a strict cancellation policy in place for long terms. 

When you break down the numbers by individual properties using the first purchased property as a templated for the additional properties purchased however, you will notice that the numbers being used in the example are not scaling correctly.It took me some time to figure out why the numbers were not scaling and adding up correctly but I finally believe I at least partially figured out why the numbers didn’t add up.By the end of year 3 the 3 properties are owned for the following lengths of time and reflect the correct numbers associated with that length of ownership (loan balance, equity, property value, etc).Property A - owned 3 yearsProperty B - owned 1 yearProperty C - owned 0 years, it will be purchased at the start of year 4But by the end of year 4 the properties should reflect the following years of ownership with their respective numbers associated with the years of ownership (loan balance, equity, property value, etc).Property A - owned 4 yearsProperty B - owned 2 yearsProperty C - owned 1 yearHowever the summary total numbers that were provided in the book for all 3 properties at the end of year 4 did not add up correctly.

I just started watched a lot of videos on BRRRR, house hacking, and whatnot on Bigger Pockets.  

In essence you have to prove your house isn’t worth what they say it is worth – and since they started 15% below market – you have to be able to justify the argument that your house is worth (say) 25% less to get a 10% reduction in your taxes.  

In my opinion, it is the best way to get started in real estate investing.

Meanwhile, the deed is placed in escrow.

The agency thing MUST be sorted right from start, that's clear. 

Does anyone know of solid courses or information I can use to get started? 

Currently, looking at some properties that have renters in place already.
