This strip was built in 2018 and we bought in mid 2019 and soon after we bought we found out that previous owners were giving this tenant 20-30K in TI and all kinds of promises to get him to sign (of course they then raised the base rent higher) so they made the strip 100% occupied and raised NOI. 

If you'll be occupying part of the property and renting the rest, that also implies it's a multi-family property, which implies there will be common areas that you'll be responsible for maintaining. 

I’m curious as to how as a new owner and landlord (at least till my portfolio grows) one goes about introducing yourself to the occupying residents and setting expectations and or getting know the situation of the property you bought.

If it's an investment property, rates may not be as favorable as on owner occupied. 

They also make decisions good/bad for your investment so it depends on their interest (less rentals for a more owner occupied, paint the exterior, maintenance, etc.)The positives of condos are:1) You can get in for a lower price than SFH in certain areas2) HOA is a deduction as a rental3) Condos in general require less management from me.  

The biggest issue is regarding non-owner occupied single family dwellings.

this is what they gave me for numbers. this would be owner occupied and credit over 800. 

Two answer your question if you plan on occupying one of the units then you can do 5% down IF you make less than 68k a year.

This would be an owner occupied property.

If I sell this year I don't need to pay Capital Gain tax (Was in that home till Jan-2018, after that tenant occupied)- Current rent is 1595 per month (Current Mortgage payment - $1968 includes property tax ,insurance etc).
