I have no clue why'd they'd advertise it otherwise, since I think every buyer-written PSA should have a "property must meet or beat appraisal" clause in it.  

You work with your contractor to get these broken down into Material & Labor costs for each item on the renovation.

Would it be silly to consider new construction at this time in 2020 given current material costs?

You can advertise it on BiggerPockets like I do (https://www.biggerpockets.com/...) and meetup.com.

I don’t even have time for the friends I have.I shy away from telling people I invest so much that it’s not on my social or any other form of advertising.

I see some people who only do internet advertising/ social media and email but it seems expensive to scale and not a super proactive approach.

If the house was in a hot area, 2 beds, might be OK for a homeowner, but the fact that the house is in such bad shape tells me you're not in that kind of neighborhood.So, you're exit strategy is probably fixing this to rent, which means it won't be  using extreme high end finishes and that will save you some money for materials.

The one flaw, which is not judgmental of your position either, but rather a fact that bears itself out over and over, as pointed out by Nicholas Nassim Taleb, having studied his materials very carefully, is that with the black swan manifesting itself, as a bad roll of the dice in Vegas, I could end up not only cash poor, but house poor too at the same time, and then really in a bad position. 

Just take into consideration and try to find quotes for:-lenth of trench needing dug (service line to home)-water line and other materials required-labor for what you dont want to do-grass seed etc to restore yard-extra $ for when you cut thru something when digging that wasn't marked
