What are some of the challenges an owner would have accepting this type of deal.  

The whole reason FHA developed a short sale method is to reduce the loan balance down to reality, down to what the home is worth, down to the value of the collateral at the bank accepted. if they had the cash, they wouldn’t be behind on their monthly payments.You're right I overlooked that part.

Because it assists in the first degree of action, not being a ready target.

However, since I was already negotiating with them, they allowed me to accept the newly posted price within 24 hours, which I did.Now, I have two options: I could fix and flip it with an estimated $200K rehab for an ARV (After Repair Value) of $825K, having purchased it for $465K.

All three generate leads from insurance claim residents and traveling professionals (medical and the trades).One of the advantages of FF has been that it's forced us to have systems in place to create leases, accept security deposits without co-mingling and provide "live" customer service. 

their are lenders though that we wont accept offers if our buyers are using them and Rocket is one of them.

When police finally arrived the gang was all gone and police said this happens and finding them is almost impossible as they do not stay at any hotels and drive down from the Carolinas etc. to cause problems and mischief.I came back and took martial arts for decades and made it up to 3rd degree black belt.

He told me that the house is pretty far gone and needs about $110K rehab on a $90k purchase(I spoke with the seller after our walk through and offered her $90K, she verbally accepted and is going to come up to the house location this weekend.) 

My timeline for turning over vacancies is strictly four weeks, which is the maximum acceptable period between a tenant moving out and the arrival of a suitable new tenant.

I’m willing to accept higher interest rates on a line of credit as the overall $$ amount is significantly lower than refinancing an entire property at the above mentioned 6-7%, not to mention restarting the amortization schedule all over again.
