Should we reserve the equity for EMD and rehab costs while applying for loans through bank/lenders to cover purchase price?

There is a line on the Pennsylvania Association of realtors Agreement of Sale that says unless stated otherwise it is split 1% and 1%, but if you agree differently with whomever you are under contract with, you would fill out that section and then that is what would apply. 

I was almost able to close a delayed financing loan with them (to get my cash back out from a cash purchase without having to wait any seasoning period), but it ended up not going through since the cash I used to fund the property came from a partnership, and I was applying for the delayed financing in my personal name (doing this to get lower rates, then will deed the property over to the partnership's LLC).  

Should I wait to apply for a loan, until I get my 2019 taxes completed, in order to get a higher line approved?

@Robert Koncal I think the confusion is that this is two different islands so different County's and zoning rules apply.  

Whatever prior experience or education you have can be applied to real estate.

Some of the recommended number and rules on BP (i.e. 2% rule) do not apply to all markets.

I don't think a Subscription Agreement document would apply because that implies that the Investor has an ownership stake.

If not paid, late fee is applied.
