I think experience and the amount of advertising you do is what makes the difference.

When several of our multi's were originally purchased & had lower rents, we had a woman from a random social services group, (had the ID badge # etc) ask a LOT of questions about the properties.

I know this part of my response will be pretty unpopular but I just wanted to put it out there.But, on the business end of things, I can 100% understand not renting to the person because it makes your multi-plex much less attractive to potential/current tenants in the other units. 

Another big question is to what degree you should be using S179, taking into consideration IRC Sec 199A only applies to tax years 2018-2025 at the current moment. 

We’ve moved on to small multi-family properties.

Focusing more on the multi-family practical system for US markets. 

Just want to understand that if you have a long term rental property, would’nt you buy new (cheaper) appliances and get a multi year (say 5yr) cover?

We’re working on getting our first property, our plan is to buy a multi family.

Any recommendations on advertising that has been fruitful in finding new leads?

., a better long-term approach may be to sell the properties and roll the proceeds into a small multi-family, 10-15 units.
