Yes, they can be slow with the first payment, but as long as the HUD paperwork is complete (essentially a promissory note here), the money always comes.

This requires more than I can type here in this reply, but essentially there can be more moving parts unless you do it in a sequence.  

To replace your income you need to flip a lot of houses, I'd do the math with an average 10-15% profit margin, because you have to account for some turds.The other opportunity is to change your job and take out the element that you hate.

When the tax base disappears so do essential services.

Also, what others have said, the personal touches on what is in your place (e.g. providing all the essentials instead of having people buy TP, coffee, shampoo, etc.) and the quality of those items (no tattered towels, stained sheets, etc.).  

More states are creating "just cause" eviction laws, essentially stating the landlord must allow the tenant to remain in the property except for a few specific situations.It won't end well.

Essentially, your new replacement property will consist of (1) a thirty plus year ground lease on the real property you already own; and (2) new capital improvements made on the real property you already own pursuant to the new thirty plus year ground lease.

Essentially 100% financing leaves no margin for error.

I host a group for midterm rental operators and I had 2 people in last week's meeting essentially say the same thing.

I essentially present to them my numbers of what I can redo the property for, and they loan me 80% of the ARV basically no questions asked except for an appraisal.
