I stayed and managed a portfolio that got to be about $20 million in commercial property, I left for a while but recently they hired me to come back and help run the portfolio which is now closer to 70 million in value.

I'm a newbie investor and I'm trying to use the BP analysis tools to figure out if a property would make a good investment.

The garage apartments in the back are excellent for singles or students because they're smaller and usually a little bit less on the rent cost. if you'd like to look up some examples of those setups here in Houston and you're using the BP insights or other data tools, look up zip code 77004, 77005, and 7700 6.

Most county property appraisers have an online tool to calculate what your property taxes will be.

I would strongly consider self managing using the tools that Vrbo and Airbnb provide.Drop all this in a spreadsheet and see what the net profit could look like with a best and worst cast scenario.

BP has various tools available to help you analyze your deals (rental, flips, wholesale, etc), feel free to use them: https://www.biggerpockets.com/investment-calculators 7.

It seems that there is information overload often and so many people offering their own built paid software tools but it is hard to know what is right for someone who wants to learn the details and RE from the ground up. 

Will you do your own lead generation or do you want tools for leads or even a team that divvy's out leads? 

I was in commercial sales and then oversaw a Multifamily investment portfolio of 700 units across 75 properties 100 mill in value.

It is invaluable local experience on rents and costs personalized for your potential property.
