As I mentioned as always there is a significant "back story" that extends far beyond the scope of my relationship with this forum.

Because we are buying the property with the cash we cannot extend or get out of the contract because of a loan contingency.

I brought in my carpenter to patch the roofs, ceilings and floors ... and to extend a closet to capture the space in one building and extend two kitchen to install apartment size en-suite laundry in two units at another building.If it's not being used and it is in disrepair, I would remove it at lease to below the roof line (ceiling of the top floor).

Negotiate and get it as low as possible (say $460K).Then put a 90-day option to buy on it with a $100 option fee (with a right to extend for another 90 days...giving you essentially 6 months to tie up the property).Market it like crazy (put it in the MLS, put bandit signs, Craigslist, etc.) to sell it to an end buyer who is prequalified for a mortgage for $610K (lower end for a quick sale).Equity partners won't work for a mediocre deal like this.If it's not cheap enough to wholesale, it's not cheap enough to partner on.Even if it's not cheap enough...you can still make money on it.Let me know how this deal goes.

The heir opened probate bc their extended family is kicking them out of the house.

One way to negotiate this is to help the seller understand that if they are willing to accept payment for their property over an extended period of time, you can pay them a price above market value.

I would give them the option of extending 1 or 2 years maybe with a slight increase but not $100 increase.

And I use "irrelevant" as well, LOLAs to the chart of accounts, you don't break down accounts by the section or part of a property like porch or bedroom, but by it's depreciation schedule for materials, like carpet, appliances or roofing.As to permits, inspections and other soft costs, you may need to take those out when presenting your basis for financing, depends on what the significance of such fees might be so I suggest you break them down by hard and soft costs (hard costs add value and extend the life of usefulness), but for taxes Steve is correct so you'll need that with each property

When I tallied it all up, I could be out-of-pocket 9-12K, by the time I was receiving "market rent"A few days later on my morning run, I worked out how long it would take for me to recover the delta between the rent being paid by the current tenants (who had been there 8-years) and the 'cost to get to market rent' {which was ~$200/mth more} ... that number was someplace between 3.75 & 5 years {more if I had an extended vacancy after renovation}.Along with that revelation, it also occurred to me the current tenants would be very aware they were paying below market rent.So we all sat down and talked it though.

I have read about extenders but know nothing about them.
