Personally as an investor, we have recast our growth goals several times over the years, but ultimately if you invest for your lifestyle you don't need 100s of doors - that is actually counter productive.

A main component of my team is helping investors find multifamily properties around the greater PHX area.

Once they have seen the property and are interested, the prequalification and background checks will do the rest of the work in weeding out undesirable tenants for you. 

In your case going to a fifth unit as noted above could actually reduce the value, so I'd be cautious of that since that materially degrades their collateral.

Essentially, worst case, how many months can you carry the property?

Is the property rentable? 

By focusing on cost-effective improvements, investors can significantly enhance property value.By first Identifying which renovations offer the highest ROI—typically kitchens, bathrooms, and curb appeal. 

You make $7K on the $175K property or $40K on the $1M property. 

I looked at their books at that is their actual expenses at this point.

Thanks to COVID, for a couple of years, you can actually make enough money to be cash flow positive even if you hire a property manager AND have mortgage payments.
