Tax Adviser has a great read on the topic, linked below, fairly technical, but gives you an idea that it may not be as black and white.https://www.thetaxadviser.com/issues/2012/aug/clinic-story-0...

Just need to know the black and white number on what you need to get in at! 

It is in black and white from literally THE source:  https://selling-guide.fanniemae.com/Selling-Guide/Originatio...Now for the good news.

So why can't it be more black and white?

I would always stick to a price that is good (black and white) on investments, the numbers should not be gray. 

I've seen A LOT of issues with new construction: using the cheapest materials available and cutting every corner possible, gaps between sill plates and walls or around windows and doors that you can see daylight through, offset sewer lines because of settling or someone driving heavy equipment over the line, black mold in the walls, testing positive for meth, foundation settling (harder to see it or predict it with newer homes whereas old ones have already settled) etc. newer definitely isn't always better.

It was initially a working class neighborhood, mostly black, which had the navy shipyards as a main employer.

I also need to remove lot of trash (black trash bags, etc.) that is inside.

I would hate to see you get it and they move out the following month because they are on a month to month lease thus removing your income stream right out of the gate.I would get an inspection on the property to make sure there is not a hidden issue of Black mold or asbestosis and such problems as maybe a leaky roof.

@Ivan ChirollaThis is not a black and white matter, and would be best addressed by speaking with an ERISA Tax attorney.Technically, a parent in-law is not a disqualified person to an IRA.
