Quick questions getting started - 1) Which app or system do you use to manage the details of your properties?

I wish life worked that way....Costs you need to understand from your servicer are boarding fees, servicing costs. if there are extra costs for tax and insurance escrows, if their costs change if the loan becomes non performing, how much $$$ to send a notice of default for non performing notes, and how late fees are handled (I have seen some keep all late fees, some split them 50/50).To calculate yields I use the 10bii app.  

Any tips are greatly appreciated.

Any tips on where to find these would be greatly appreciated.

I would like to put it either in a google drive excel, a cloud based something, or on iCloud password app, but all of these are not secure.

Do you have any advice, tips or tricks on FHA/VA loans with multifamily, land or investment property purchases?

No agents involved either side.Any other tips when buying for sale by owner?

Some tenants I know will not be using the app and will be paying by check.

Key tips for success?

I'm planning on going to real estate meetups in the area (I'm in Austin, TX), does anyone have any tips for starting conversation/building relationships as I'm just starting out at these events?
