Owner should not agree to binding arbitration if he has a choice because arbitrator will be looking for a compromise when there is no reason for one in this case.  

MSHB is ALWAYS my first choice.

We were interested in the larger multifamily project, but this was included as part of the deal.

If you're getting 15- 20% NET income per year, YES, it's a difficult choice.

I have seen some companies handle all aspects of general maintenance for a property for a flat fee + call outs for larger issues. 

You could also combine a down payment with the remaining entitlement for a larger loan amount.

HML just went to private money to give the allusion that you are going to find some rich doctor that is going to lend you money at 5%. private money  hard money is quite competitive these days.. you can plan on 2 to 4 points up front at close and 10 to 15% interest  plus junk fees and rehab draw fees appraisal fees etc etc. some of the larger national lenders have their pricing very well spelled out on their websites you may want to get a baseline from themKiaviLima one Lending oneetc etc..

When asked I would contact a vendor of my choice; the landlord said it can only be repaired by the vendor of their choice.

Besides, if I'm the only one writing the checks, then he has no choice but to work with me.

Typically I try to stick to 2-4 bedroom single families as larger homes do not bring much more in rent but more in repairs.
