TIPS?

I used Listsource before for single family home and  would like to know what other strategies/sources others use or any tips. 

These are great tips!

Any tips of converting/adapting my apartment complex underwriting model to one more appropriate for MHCs?

On the other hand, it's apparent in the county minutes that they're at a loss for what to do with the property or who would potentially want it given current condition and zoning.Does anyone have stories, tip, or tricks for buying properties from their county's "delinquent tax list," before they go to auction?

(Pro Tip: Everyone loves an Amazon gift certificate!)

One key tip though, make sure you have your refinance lender lined up. 

The HOA is well-funded, everything on the property has been recently renewed (roofs, roads, pools, gardening, etc).I am curious as to whether market conditions are shifting because of local short-term stay bans (which might have opened up a lot of housing stock), COVID, over-building, or any other factors.In a town of 20k people, apartments.com lists around 3800 available rental units.

There's not any better financial book that gives strategic AND practical advice on finances for the business.I'd also recommend Gary Keller's The Millionaire Real Estate Investor because of the practical tips offered in the book.

Any advice or tips for my goal and path is much appreciated.
