I will need to get the exact numbers from the lender tomorrow on what the new payment will be on the initial two properties and the new one to do the math....Easy enough to calculate based on the numbers you gave - Principal balance of $214k, 25-year am at 4.9% is a P&I payment of $1,238.59. 

As we are fixing up the parks and selling manufactured homes in spaces, we have been using seller financing since traditional financing is very difficult and expensive for the buyers.

Why don't you read through $100 worth of books on how to wholesale, ask some questions here on BP, and then see if it's still very difficult to grasp what you need to know?

My back up plan was that I would force enough appreciation via my fixups that I would be able to get a loan for the balance owed plus most or all of my out of pocket expenses if I didn't have them sold by 1 year. 

The rub with Agency is that it can be difficult to qualify for. 

It seems like it is fairly difficult to find the cash flow with such high purchase prices. 

I find it difficult to believe that there were no red flags during the process. 

If its a hot market by you, the LA probably isn't answering because they know they'll get offers in w/o any questions - it makes you seem difficult at this point when a price or your qualifications haven't yet been established.

But it could be more difficult if you work 6-80 hours/week and buy properties that require extensive rehab/have lower quality tenants. 

BM is out too.As soon as someone starts lying to me and being difficult, I'm looking for an opportunity to get rid of them.
