It’s worth mentioning that while many people prefer Booking.com for its convenience and reliability, this doesn’t mean that other platforms cannot offer the same level of service.

They often refer to it as 'certainty of close' when reviewing offers.3.

I came across a firm (KBKG) that offers a $400 DIY cost study (paying for a membership). 

Now you have enough to pique your interest further, but it still gives me the hee-bee-jeebies.Next step is to ask to see the offering documents regarding the syndication.

Here are my responses to your questions1) Not my area of expertise, but the numbers on this are very strong2) I'd generally lean towards building the CFM, but strategically selling some properties when someone gives you a offer you can't refuse.3) Most HMLs would lend you 75%-85% of your purchases prices plus up to 100% of the rehab costs (though some HMLs like to see the rehab costs at or below the purchase price).

It sounds like the Seller does not want to commit until he knows the deal will go through, and until that time, he wants to be able to entertain other offers. 

The home was on the market for over 200 days, the builder offered 15,000 discount.

Your maximum allowable offer. 

Multiple offers situations are the rare exception, not the norm.

When I asked my agent about options to back out, he didn’t really offer any advice.
