My hypothesis is that when SIP is lifted, sellers will get back on the market after waiting months and increase inventory and previously worries buyers will also come back to the market generating demand and competition/bidding wars.

Those can generate cash flow for you, though they will typically not be very aggressive in rate of return.

. - Property is purchased at 520,000 for example, value is 720,000 currently through comps. it is in terrible condition im assuming due to the exterior work. after reno and transitions, I believe it would be valued at 850k-900k easy generating $3,000+.

My background in technology (ssserv.com) provides marketing and branding experience for lead generation. 

At 1.3% that property generates $3,250, or about 1000-1100 per unit - totally feasible.

Over the last few years of acquiring properties (https://www.biggerpockets.com/forums/48/topics/790712-turned-30-own-12-units-generating-an-average-13-cap-rate) my lead traffic for vacant become a mess...

@John Kelleyreally depends on exact location, current zoning, what type of demand generators in the area, what’s around it etc...lots of questions to determine highest and best use.

It is half of my grandparents original estate that's been in the family for generations.

It's a trope, but real estate is a relationship business that compounds on itself as you generate more and more happy customers.So keep your job and save up for that 6 months' savings that @Gregory Schwartz called out - that's a pretty standard figure for about how long it takes to see any sort of money coming in. 

The cost of constructing an additional 7 units is between $1.3-1.4M and would generate a projected $118,000 annual rent for a total of $210,000.
