Hello BP family ! I had an interesting topic my business partners and I have been discussing for quite some time and I would like the advice of you all. If you had 16 properties that you are renting out , would you us...

I will occasionally test out swapping and using RankBreeze to track any difference, but I usually go back to my favorite hero photos and top 5 anyway.  

Testing the market may get you an offer you're looking for!

Seems interesting run a split test see if it works out for you.

When analyzing properties, it's helpful to run a rental stress test to see if the deal can withstand unexpected challenges.

I gave it the Nickproof tug and it passed the test.

A duplex is more flexible as you will have privacy on your side and can test out any strategy with the other unit ( LTR, MTR, STR, rent by the room).

Trying to “focus” on multiple markets at once is kinda an oxymoron—by definition, you’re not really focusing.
