I have been reading about the 80-88% rule but I am worried it will impact my offer and not being accepted. 

It’s a bit hard to stomach or accept that I would be losing 10K if I walked away from the deal.

I would check with your municipality to see if it is acceptable and what the permitting looks like.

I just had my first off-market deal accepted.  

But finding the right one in which the numbers work out and the Owner will accept owner-financing, etc, takes a lot of research and patience. 

The generally accepted definition of a small business is a firm with less then 500 employees and depending on the industry somewhere between $750,000 to $38.5m in annual revenue.

It would seem cash flow may be impacted some (market value seems untied to rent value), but it seems likely that I'd continue to pay my mortgages, and unless the banks want to be difficult, they would continue to accept my on time payment. 

We are in the process of house hunting, and finally received an accepted offer.

@Chi Ta I’m an Architect and what I do for my developer clients if they want to take the risk is to start the plans as soon as their offer is accepted.

But prices are insane out there right now and anything remotely acceptable on the MLS sells immediately.Its pretty easy to self manage.
