He came to me saying he has friends who are from Greece that have about $4 Million Dollars they are looking to put into real estate on the east coast but don't know where to start.

He pays on time, which is what every tenant is required to do, he doesn't bother you so you can be a lazy landlord, the neighbours like him and the costs of repairs is irrelevant.  

The neighbour agreed to buy at 1.3M, buying cash and will remove garage.End of August I will have my down payment back and 0.6M in company account.

Buy my Neighbour house as a primary resident. can I still use DSCR loan as a down payment and all the other cost?

When global interest rates followed T-Bills on a fast upward trajectory, these countries defaulted on their debts.In today's global economy, when a country like Greece even sneezing in the general direction of a default can cause money institutions to panic, it makes me wonder how these same institutions would react to an interest-rate-related cascade failure due to interest rate hikes.

They should have been more attentive, but honestly if the tap on the side of my house was open, unless my neighbour saw it, I wouldn't know it was open. 

Had she checked on the neighbour and let you know, it might be a different story. 

I called in my parents house today and they know nothing of my learning about property investing.Any how they happened to mention that a neighbour of theirs has said he is going to sell his house as he is sturggling to pay his mortgage since his partner has left him!

Block your neighbours calls.

Credit union possible if they have mortgage program for their own portfolio.You can do some reverse engineering by checking the mortgage of your neighbour and find out who is the lender , I know few direct lender.My condo is non warrantable too, usually you get quote from a broker and they will find the one that fits into your situation , if you can get 7 percent rate that’s a blessing lol
