Are there any good resources you would recommend that give broad overviews of the markets and then some that provide more detail?

Just to throw out some more details to see if you have any thoughts...So I'm not a realtor and won't be on the "transaction side of the sale of the relinquished property".

Details: Built 1947, ARV 210K, 1050 Sqft.I know it's best to get a contractor to get an exact estimate.

The plan does not have to be extremely detailed, but you should give yourself an outline. 

@Costin IorgulescuWhile there is technical merit to the differentiation between the tax performance of passive real estate held personally and within an IRA, the argument misses the key point.When investing your IRA in any asset, you are not comparing that investment to how it would perform in the after-tax world. 

I have agents, title companies and escrow, now I am looking for a General contractor who can assist me in the finer details of the remodel. 

I also tried a few of the online banks mentioned above as well - none worked.It can be done- but there are a few hoops to jump through and costs a bit.I use a US-Israeli accountant (offices in both countries) who can facilitate this- PM me if relevant and I am happy to give you his contact details.

I looked at the place and believe that I can sublet it for $700, creating a  $40 cash flow with no money down (so technically infinite returns).

I do have the rental income of all the properties but the valuation he provided didnt provide me with any details with how he got the price per square foot that he used.Is there something i'm missing?

I'll spare you the technical details, but this is a situation you'd want to avoid.
