As in the US, very few buyers will buy a property online - most of them will engage a team that knows the market, neighborhood and can provide excellent service.

That's tough to say.A 6 unit would be considered a commercial property and likely will have a higher interest rate as well as require a bigger downpayment.Usually they want you to wait 6 months to refinance.I don't think you will get a 4.5% interest rate unless you have excellent credit as well as a good percentage of money down on the loan.  

Our strategy is only possible if you have a great credit score/excellent limits on the cards, and also-- my partner and I do 90% of the renovations ourselves.    

My personal Docter had been telling me for about 30 years that I was in excellent shape and my chiropractor saved my life with suggesting I get a head X-ray that is called a MRI.  

Interest earned by an IRA as a purpose is excellent.  

He is an excellent carpenter.

I have excellent credit, but no experience.  

Hopefully excel to allow slicing and dicing of the data.

Although our partnership worked excellent for several years – AND were still friends, I’m not big on JV or partners but I appreciate the idea. 

@David Marsceau Excel is probably the go-to for many people but I can only speak for myself.
