When I made that decision I described, I wasn’t educated on assets/liabilities and what impact that new debt would have on me.

Although I prefer doing a refi vs a HELOC because the added cash out is termed out over 30 years and has less of an impact on my cash flow, my concern is I'm not sure if my property will appraise high enough to conform to the 75% LTV with the cash out and I dont know how long the process will take (2-3 months?).

It came with existing tenants, one of whom had a job impacted by COVID.

If occupied, will the tenant's "neatness" impact the appraisal value?

These are specifically designed with the long horizon in mind and are much less sensitive to rapid market swings as well as providing inter-recession protection (probably a phrase I just made up) but it is what is says - letting your wealth in a way where recessions no longer impact or concern you. 

Under normal circumstances this would not impact your personal credit if structured correctly.

If that is the case, jacking up a temporary brace that spans the impacted joists will be step one.  

In addition, prices for hospital care (+0.4%), home furnishings (+0.4%), and airline fares (+2.6%) were key contributors, while heavily COVID impacted industries like autos and recreation continued to have price declines.

This will have a huge impact on what you do next.If it is a mobile home, you will not be able to get an FHA or any other kind of agency loan on the property.

You want to understand the impact.
