Seller agreed to install a new hvac, hot water tank, and furnace before I can do the do the inspection now. 

I agree with Joe, talk to a title rep.

@Anita Z.I agree with @Grant Woodward about looking at the reviews.

I hired a contractor with a solid reputation for working with international investors, and we agreed on a total cost of $495K, to be paid in stages.

@Ludwig KoenekeI agree with @Jonathan Greene that you shouldn't pay for an appraisal twice.

I agree.

Okay I agree with most of your points but WIP purchased this deal DECADES after it had restrictive zoning.

If you get a house full of veterans that know each other and agree to live together I wouldn't think you'd have many issues like this! 

2.Create a direct booking website and set up an escrow account where guest payments are held and disbursed to the property owner and cohost according to agreed terms?

And I buy the seller carry back notes for those that want to cash out.I agree with jack Bosch I saw him at a rich dad event and his stuff was very dated.Its not a complicated model you buy low sell for more..
