I haven't slept yet, so I forgot about the other party wanting to invest in your project, but my prior content is still relevant.

The investors have been very difficult to work with from the very beginning with grinding us down on our prices to a very very slim profit margin (almost making the job not worth taking but we got so far in deep we accepted any way).We originally asked for a 50% deposit prior to work starting as we have never worked with this particular investor and then we would collect the remaining balance once work has been completed.They had two other bids but decided to go with us because of the quality of our work as showcased in the portfolio we presented to them.Well, they managed to get us down to 25% of deposit (initially they asked for 10%).

Someone doesn't have to be first in line to record to foreclose and wipe out those behind them, as long as they recorded prior to those behind them.

Depending on what market you choose and the conditions of that market you may want to sell first prior to finding the next property.

Right after you close on an improved property get an insurance policy that will protect you if there is a loss.  

While I generally don't give specific details as to why we are terminating (we can give a 20 day no-cause termination), you could let them know that your contract/policy is no more than 2 people per bedroom. 

I also learned how to talk with motivated sellers and learned negotiation skills prior to me wholesaling.Wholesalers who are experienced real estate investors tend to be good wholesalers because they know their numbers, their market, they know marketing and negotiations.

I don't know the specifics and if these are hard policies or general practices.

Why is everyone ok with discounting escrow but have no problem paying crazy points to hard money lenders, full price owners policies, and 6%+ listings?

Prior to the lease ending, they said they wanted to stay another 3 months.
