Yes, you're buying cheap, but add 3 lots of all that capex and all of a sudden the deal doesn't look so good.Get a home inspection if you can to identify this stuff, then you can factor any major expenses into your plan.Assumming you get that far and you know what yoy need to spend total, then you can look for funding sources to pay off the existing debt. 

I was in the process of entering an amendment for a reduction of rent with my landlords when landlord b suddenly passed away.

many agents and sellers want to see how much loan $ you are approved for, and/or cash on hand to afford what you are offering to buy, in order to take you seriously enough to go through the trouble of a showing and the time negotiating offers and terms (lest they waste that time with any and everyone not qualified but just interested in wheeling and dealing to see how low you will go or whatever).the moment a potential 'buyer' drops the W word, there's this implied expectation for the agent/seller now to suddenly take the wholesaler on their sheer merit - as opposed to on any financial qualification to enter into a binding contract - that they dont have any interest in the property actually closing *unless* they find a buyer to make a profit off of before the contingency period runs out.  

Nonetheless, having the game suddenly changed significantly 9 years into a loan is quite aggravating. 

I am currently in the process to buy my 4th house bank financed and all of the sudden a property, that I was monitoring for a while, becomes available.

I brought up my concern about the market suddenly catching wind of this hidden gem and buying up the remainder of the lots or the seller raising his prices.

Suddenly your buyers agent receives zero commission on the deal paid out of the sellers proceeds.

Market rents have climbed and a sudden, significant increase would be a huge shock.

Because I like the properties, but just buying the property I would immediately have to start raising rents to market rent or evict some people if they're unhappy about the sudden dramatic increase in rent.

I'm thinking whether we will see similar Lehman's collapse and whether there will be "too big too fail" so gov. has to rescue their friend, and QE will be restarted..... this is especially true for bank that's financing company like Coinbase/Celcius/any crypto company.Also my bet is if tomorrow's oil price goes back to $80 (like it always happened) then suddenly everything is back to normal.
