So, for example, when you find a previously unknown issue that needs to addressed and you want to keep the Costs in line with your budget you can adjust the Scope of Work and possibly the Time!

Combine that with unknown changes it’s just too risky for us. 

Numbers are divided into known and unknown.

Dropping $100K on an unknown entity is a little scary for me. 

Make it even worse for claimant by firing the original Trustee lawyer (resign) and assign yourself or another different lawyer as new successor Trustee, the claimant will cry going on wild goose chase that's way more difficult lol (the original lawyer will say "I'm not the Trustee anymore and I won't tell you who is the Successor due to ACP rule, that's your problem to dig up in other unknown planet, not my problem")Not recommended to use your home address also when recording deed and when filling out Quit Claim form, best to use business address of Registered Agent outside State, they charge around $60-$120 I think. 

If they were unable to, how did you account for the unknown functionality of the systems such as water, gas, etc.?

@Bernardino Graziano if it would take 7 years then many investors would suggest selling; especially given the unknowns of the next 24 months.

On EVERY single pre-foreclosure sale (whether a short-sale or not) I ALWAYS include the following terminology right in the body of the offer itself:"This offer is expressly contingent upon the approval of the seller's lender(s) and/or any other unknown lien-holders".I was told early on to include the "any other unknown lien-holders" provision as protection for both the seller(s), as well as the buyer(s)...

Projecting authority with a range of topics from home maintenance to financing will help bridge the gap between clients and a yet-unknown seller.Accruing blog visits is a whole other story, but in this day and age a well-maintained blog is an essential part of consistent lead generation.

I think it is harder to forecast the rental scenarios since there are so many more unknowns, but I made assumptions based on my 18 years of rental history.
