Also start looking for deals to see if selling would beat what you are earning now, if it does not then hold till something good pops up. 

Some offers might get ignored or outright refused, but all it takes is one offer to get accepted or countered to start negotiations. 

Hawaii law requires an on-island manager, but in order to qualify as an active business I’ll need 100 hours managing the property so hiring a regional manager may hurt my tax write off plans.

I had one lender who was taking issue with anything that was greater than 1 hour away as they were concerned with my commute to my W2. 

When I started my preference was to work with realtors.

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.

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

It sounds like you just started your RE journey.

I didn't like this location a few years ago, even though it was starting to turn.

Overnights are very very transient and come with unique challenges, think about these like a Motel 6, people arriving at all hours, tired, just need a place to crash as they make their way to their final destination.
