20% is not high for managing a STR.

You can buy a set of five for under $300, subscription for the recording software is $10 a month, then the cost of WiFi or hotspot.If you've already had a couple break-ins, you are obviously in a high-crime area.

If you have large debt with a high interest rate, I would consider paying that off before getting started investing in real estate. 

@Cathy Ries Yes, tax planning before acquiring rental properties is highly beneficial, especially given your situation.

In a climate like this with high rates, probably better to use a Heloc so you keep the lower rate of your 1st lien.
