I'm looking for a deal but as usual it has become harder every year with such limited inventory.

Ditto what the others have said (usually tenants pay their own utilities), and require them doing so in the lease (especially if the house has gas on top of electric and water).   

They usually have 2 to 3 hours a day when their kids are sleeping. 

If you are not going to be in the area while it is being leased, I would recommend finding an experienced co-host in the area that can carefully monitor things and help keep your AirBNB rating high.You can find a lot of experienced co-hosts through AirBNB and usually only need to pay them 10% of the guest fees. 

Let them know you understand that their loan is usually 12 months or less. 

I usually tell people 1 hour but that's because I work in Miami and there tend to better deals in Palm Beach & Broward county. 

To use cash flow to fund the living expenses usually takes at least 40 to 100 doors.

If you never seen a scope of work then juts imagine a list of work that needs to be done with detailed description and itemized. 

very very very common approach.. but agents are not going to get a seller to lower price just because they are double ending.. what usually happens is if there are multiple offers agents being human.. will slant their double ended deal .it does not equate to you getting the agent to sell the property for 25% less than what it could sell for on the open market.. agent would get in big trouble.

Question 2 all in i would be around $60,000-65 worst im usually at 50k but changed my business model and have new team faster and better work.
