I am bullish on the FHA 203k and home-style renovation loans that allow you to leverage the cost of your renovation as part of your mortgage, which is just an insane deal, in my opinion.Do you have a specific area where you want to purchase?

If you aren't going to be living in CR full time as you try to execute the deal I do not think it is physically possible for you to obtain a loan from Scotia Bank and not worth your time to try because the rates are so high. 

They say as I have just seen they will loan money.

Possibly break loan covenants and can't cure default, lender takes back property.  

There was also a loan grant available from the state of NH for first time home buyers for 3% down payment assistance.

It was 50K loan for 6 months at 20% interest.

Make sure you talk to a Banker or Loan officer that is well versed in both SE (Self Employed) income and also Non/QM programs.One tip I will give you as a Banker is open up a "Business Checking account" and for the next 12 months pay "Everything" out of that account. 

Loans are nothing more than networking, and strong financials which you look to have on the property.

I signed up with them about 3 to 4 months ago, then found out how expensive the loan was to get going with them and told them that I would self finance it instead but they had to cancel the loan first...they use a company called Special Financing Company..the person I spoke to at REI his name is Paul, he said he would take care of canceling the loan, but a month later I realized that they were pulling $599 out of my bank account.

DSCR recently came popular in the loan brokerage and private credit space with the rise of STRs and MTRs.Your local bank lenders will have the best rates typically.
