If none of the strategies you like and are willing to work anymore due to external circumstances, you can keep what you have from the time when some or all strategies worked and focus on preparation for market conditions to get back into your frame of strategies.I agree that currently most published strategies (at least published on BP) still work if you find the right deals.

Local (on device) storage that later syncs when web access is regained would be a slick solution.Robust backups - both online/continuous backup plus the ability to dump a snapshot of data to an external hard drive.Easy access via search to contact details.What deal(s) they're a candidate for.Ability to text through the app.When responding via email, text or phone, auto suggest a follow-up task with a drop down for when to make contact next.Calendar that syncs to your smart phone.Ability to schedule appointments with fields for location and notes for the meeting.

Bonds, cashflow, appreciation, stocks all have some degree of risk and are subject to external factors, often outside the investor’s control.

Most SW's do the usual tenant portal, pay online etc. but not all do external payments.
