It sounds like you're doing great research ahead of your first flip.

It sounds like you / your parents should just hire a professional property manager for the inherited properties.  

For this example it looks like I would need to buy it for much less than asking price if the numbers stand right, can an experienced rental/flip investor look and see if these are sound?

@Leon G.Man, it sounds like you’ve been through the wringer.

It sounds like you need a reliable and trustworthy partner to help you navigate this transition seamlessly while keeping your solo 401(k) on track.I’d highly BiggerPockets Partner for this, Equity Trust, a top-tier custodian in the industry.

The reason is the rent-to-price ratio is good so you can cash flow, and most of the West side doesn’t have a Point of Sale inspection which is really annoying.

I also advertise before someone moves out to get a new tenant before the current one leaves. 100% occupancy on a LTR is very common for me.No idea on a MTR.100% occupancy sounds great, but for a bigger portfolio or apartment complex, it usually means you're leaving money on the table.Here’s an extreme example: I could rent out 100 units at $500 a month and make $50,000.

They don't care when you try to explain all the future projects, they actually hate hearing that since it sounds like a scam, when an investor says, "Give me a good price and I will have a lot of work for you" it sends chills up their spines. 

@Ankit Lodha, as others have pointed out, this sounds like a transaction you should be able to get done.

Here is what we have found and I will probably catch some heat for some of the things I have to say, because it does not sound "investor-friendly".
