@Annie Shao I would start by reading David Greene's book on long distance real estate investing.

I have a long distance Airbnb and I’m looking for ideas for programmable locks.

@Alex Mansur A good book recommendation is "Long Distance Real Estate Investing" by David Greene, there is a digital version and audio, digital giving you access to a search option for keywords.

The long distance investor does make me nervous even with its pros. 

I'm looking at either the OKC area, Osceola County or Pinellas County FL.I'm currently based in the Philippines so all investing will long distance investing.

I can possibly consider a long distance one in cities that we travel to often like New York city, Austin, Dallas and Miami to start writing those trips off.

Maybe that is buy & hold, short term rentals, house hacking, long-distance investing, etc.  

Cash flow is not my top priority, but I do want it to cash flow at least not require me to come out of pocket each month to cover PITI and hopefully enough to cover O&M expenses (e.g. new roof when the time comes, new appliances as needed, etc.)This property is in West Oakland, within 10 mins walking distance to MacArthur BART.

Most experts project wide availability of a vaccine no earlier than the very end of 2021, which means that social distancing and home offices are very likely here to stay.

If being a long-distance investor is causing you some anxiety, you can always partner and start small.
