We rolled profits from the first year into a second, smaller condo ($170K purchase) that will bring in $50K gross this year with stellar cash flow.

The good news is you can typically roll your closing costs into your mortgage and pay less out of pocket. 

I then signed a new 1 year lease that has since rolled over to month-to-month.

If they don't use Sparefoot, then they are probably filled up, since they aren't pushing themselves to fill up.

The explosion pushed the front & back walls off of the foundation, so the house was very near to collapsing.

That being said the one thing that I see many people talk about is trying to get that first deal financed and get your ball rolling.  

I didn't disagree but I really wasn't on the same page, I rolled with it though.

@Peter Koch, I agree that a PM may not want to actually link the accounts with two way traffic, but there are APIs (I don't know if Appfolio and Quickbooks have the appropriate ones) that allow for data from one software to be pushed into another, without the second being able to access or write to the first.

I am planning to start construction on my garage ADU next month (already pushed back many times due to Covid, getting permit issued, among other things).

Focus on your "why" and use it to keep pushing you forward.
