Let’s unpack your ROI question in a way that reflects the reality of your financing setup.When calculating ROI with multiple loans, you’ll want to include all financing components in your cash flow analysis.

And @Natalie Bender is right about spreading your risk by going into multiple DSTs. 

new houses are getting sold for 600K, old houses switched to multiple offer selling model, just like some places in GTA.

for me, the ones that cashflow the most are the ones that I bought with 3% long term debt, they were new (low maintenance) and they are in high appreciating areas(just a bonus but does not impact cashflow).

When you add that: "The downpayment and closing costs would be one large hurdle"; I can't tell if you can only afford to do this once (thus tying up whatever you have saved) or multiple times.  

However, expect greater transparency and heightened consumer awareness that has come out of media attention and NAR settlement to impact the listing component of seller agency as well.

I heard about bigger pockets from a friend of mine that has successfully built and rented multiple properties in our area. 

Not calculating your basis properly between building and land, which impacts depreciation. 2.

If I was not starting from scratch, like I did myself, I would buy SFHs because I prefer their long-term flexibility, relative scarcity, and multiple exit strategies to MFH.

How does this impact AZ Real Estate and other states that will get new residents from this disaster?
