All countries are driving their currencies down since it's a short-term fix for a lot of problems for them.As far as govt being a responsible party managing fiscal policy - You've got to be kidding.

However, to do a cash out on an investment property, she can't go lower than 75% LTV, which would be $104k, that part is fine, but the rate would be 4.375%. 

I am wondering if I should try to use the sellers agent so that there is more incentive for the agent hoping that he or she could help out both parties?

As parameters are filtered down to the local team and (likely) some third party broker...they don't have as much flexibility in negotiations.

Throughout the renovation process, the lender disperses funds to the contractor in draws once the work is completed and has a third party inspector go and confirm the work is completed with each draw.

I've always let those type of situations be dealt among themselves, and I'd only advise (minimally) as a 3rd party but not as a landlord.

Not to mention that’s a lot of money.Two primary lending rules I go by for the sake of all parties involved:#1 - Put EVERYTHING in writing.#2 - Don't loan money to family/friends unless you're willing to lose both. 

All parties to the exchange must be notified that a 1031 is taking place. 

Welcome to the party sir.

There also is a section in the PM contract about the "Entire and Binding Agreement" that says that "Parties agree that this Contract expresses the entire agreement between the parties, that there is no other agreement, oral/otherwise, modifying the terms and this Contract is binding on Parties and principals, heirs, personal representatives, successors, and assigns.
