My electrician insisted in rewiring my house without ripping out the existing drywall.

Buyer go to open house directly.

It will be even harder as a young person with no life experience, and particularly no experience buying real estate. 

Also if you are selling, hopefully your agent has advised you but good practice to have a vacant unit to open the buyer pool to owner-occupied buyers/house hackers.

Tenant chose to stay in house during repairs citing Renters insurance declined coverage.

When you say "we," are you speaking about your business or your personal tax returns, or does your business flow into your personal returns because you file as a sole proprietor?  

I first started out in Real Estate by house hacking in college. 

If there was a house of interest listed it was get there same day and make a strong offer to even have a chance, this doesn't seem to be the case at this moment.

I took my thrashing as you know in 2020  I do know some of my clients that sell turnkey have been keeping the houses and doing BRRRR instead of selling them to investors that part of the market has slowed signficantly for many in that industry.

Do they do any of this in house?
