How to ask tenant/ owner to show their foreclosed home

[Grace Shine]

This REO home that I am interested in is an upscale home. The market price I'd say is around 700k and the average home here is around 350k. I am looking to purchase as my primary home not an investment home.

According to neighbor, the house was under only husband’s name. The husband left the wife a few years ago and stopped paying the mortgage since then I am assuming. The neighbor said that she is planning to move out in April. 

The seller agent, however, said that the bank failed to evict her as she didn’t agree with the amount the bank offered her.

The neighbor also mentioned that the wife is getting help from her lawyer friend- not sure what she is getting help on? Perhaps regaining home? (Not even sure you can do this in IL) Suing her husband? Not sure..

There is no liens; however, I bet the owner won’t pay 2021, 2022 property taxes, which will be around $33,000.

The home was up for auction at the county court couple months ago and the starting bid was $528k and it was reverted back to the bank as there was no bidders.

It will go on online auction soon.  would going up to 500k be a good idea? There will be a 5 percent premium that winning bidder needs to pay (=25k), unpaid property taxes for this year and last year (=33k), eviction attorney cost (=2k), cash in hopes of keys (=2500 to 20k??) repairs (50k-100k). 

As there is no interior pictures found anywhere (owner built the home), I was hoping to knock on the door with some cash and ask for a very quick tour of the home. Any suggestions on how I should word it? 

Please let me know if you have any other advice on this property. 

Thank you in advance!
