My day to day job is as a critical facility engineer for a data center, with my specialty being HVAC and commercial electrical. 

Overall, the idea is that you might be buying a building at a 6% cap rate (or less) but when you underwrite conservatively using market data that you know and are comfortable with, you can run the building better than the current owner, make the building cash flow and effectively making it maybe a 9 or 10 cap building.A good example.

Money kept in a savings account is obviously free and easy to transfer.

They're starting to think more about transferring the home into an LLC with 6 members (husband and wife x 3).

You could use balance transfer offers, as long as you are able to make the payments and transfer or otherwise pay off the balances when the promotional period is over.

Associating with those of low reputation may not only lower your own but also lead you astray by the faulty assumptions, premises and data of the unscrupulous."

So having MLS market data and analytics back then was super valuable.

We have already done a lot of research on pop increase , wage growth , job growth , % of renters , crime rate , etc. ( all from city-data, census , best-places , IRR).

I have looked at some rankings on websites and some data like that but I'm curious what actual investors are thinking and why they focus where they do.

Then just transfer the property into your LLC.
