2) What main skills or knowledge should I focus on acquiring right now that would be beneficial for my current and future real estate investments?

Perhaps for real estate pro`s this might not make sense, but to us it did, since it is not our main business.4.

We won out mainly for purchasing without a loan (yes, hard money, although strong, can still go sideways in a deal).

It's "Diversified Investors Group" or "DIG" - Their main meeting is in the northern suburbs, but they also have smaller group meeting in and around the city.

Looking forward to hearing from you guys.TIA That is a bad move to have the tenant be manager/main person..

:)The most important thing in wholesale real estate is to stay sharp on your lead and deal acquisition, as these are the main "products" you're selling.Investing in strong outbound and inbound strategies to find off-market properties and their sellers is the foundation for success.Good luck!

What they tend to realize after the fact though is the higher payments are now mandatory and the monthly cashflow is cut so that you're mainly relying on equity which although likely isn't always guaranteed. 

The PO Box mainly won't get used but in future I plan to use the address with any tenents.   

For example, on what I thought was a relatively simple project in a bathroom reno which was fully gutted down to the studs already, I had more than one quote for over $7k to run pex supply lines and rough in a shower drain and toilet drain off of an existing main stack, all of which ended up costing me about $200 in pex lines, PVC fittings, and sawzall blades.If you need any hardwood flooring repaired, patched, or refinished, you can't beat Dave's Hardwood Flooring out of Blaine - $3k spent with them fully brought one of my duplex unit's original 100+ year old maple floors back to life.If you're putting in any stone counters in your kitchens or for bathroom vanities, Twin City Discount Granite have been awesome to work with, and consistently have the best pricing I've found in the area on fully installed granite and quartz.I also have a great drywall guy, as well as a really good carpet install guy - feel free to DM me if you want either of their contact info!
