One would think that a bidder would pay $45,000 in my example (since they are assuming the first mortgage), but they are actually bidding $225,000.

Doing this will indefinitely defer paying tax on profit or depreciation recapture. 

However, aside from that, I couldn’t find much information about them, and the only online presence seems to be the wife’s LinkedIn profile (though I’ve never met her in person and am just going off her profile picture on Zillow).After submitting the application through Zillow, we attached our income (two months of pay stubs for each of us from our current jobs), work references, credit and criminal background, rental history, and the contact info for our current landlord (who just so happens to be my fiancé’s father).

They stopped paying the lender and wanted to work something out with the lender but the time is running out (ie the management company did not do any significant improvement during the forbearance period) One of the LP just emailed me and said we need to raise 65k to enlist help from this company.

If I identified the offender, I would probably bill them back for the wasted water and when they didn't pay evict them, or non-renew them if their lease was near the end because that is simpler. 

You don’t have to pay $20k+ to learn to broker loans. 

If you pay more, you won't meet your metrics and will probably have negative cashflow and/or equity.You may have to make 10, 20 or even 100 offers to get one accepted at the price that meets your numbers.This is what all investors did BEFORE the Great Real Estate Crash of 2008-2010.

I've never been to a pay laundry that didn't take twice as much drying as washing but not 10 times.   

Right now you have $1,000 in cash flow that can be used to fund other projects (seed money), pay you in profit to supplement your lifestyle, or fill in any gaps for underperforming properties.  

I understand I'd take a pay cut being an agent for the first few years, but in exchange, I'd be learning about the market and building a network as I move towards Commercial multifamily.
