Probably so much that you'll be overwhelmed , but please remember that there's: Acquisitions (buying of Existing Self Storage Facilities); Development & Conversions (building a facility starting with dirt or converting an industrial warehouse or Big-Box Retail store into Self Storage);  Raising Capital; investing in a Syndication, & so forth.And there are plenty of folks here on Biggerpockets who have started forum topics, added posts, and greatly contributed by sharing their knowledge & experience. 

I'd say go up to developers and say I'm willing to do your s*** work so I can learn (if desperate you can say for free).Most developers can use the help, you need to convince them you'll contribute, won't screw up stuff and have enough knowledge not to ask for help every 5 minutes.

My tenant is reasonable and understands their responsibility in this, but the repair cost will be too high to expect them to contribute significantly. 

Actually what I meant by that is I can’t quit cleaning and just hangout and be a stay at home mom and not contribute to the household.

Does contributing maximal to your solo 401k affect your traditional IRA contribution or do they work concurrently?

(getting some credit from the buyer towards closing costs)2) convince the seller to do the wiring job before closing, and for me to contribute the electrician costs.Note: the seller had a cash offer that was not much below to what I offered so they might not have a strong motivation to do the work before closing.Any advice on how to save this deal??

Now that you appear to be more in that position of having capital where you are putting up at least 50% of the capital I'd be very skeptical about giving equity away without a capital contribution.  

I can contribute about 30% (but would prefer for it to be less if possible). 

We got rid of all that we suspected that might have contributed to the "sweet" scent but the same smell lingers on. 

Don't buy high to protect yourself, just buy right and make sure your monthly mtg contribution is at or below mkt rent so you will cashflow when you rent it and move.
