We have a property we very much want to buy where the low utility/property tax bills would allow us to be able to thrive living in with our limited income, so we are hoping to sell immediately.

However, I don't know if there's been soil tests, building plans, I don't know if there's utilities in place underground, if it's in an HOA, etc.. 

Previously, we utilized white spiral anchors for drywall, but they haven't been strong enough for our guests. lolThanksLee

I'm putting solar panels on a new 4 plex build so I can pay all utilities under a single payment and make life easier for everybody as it is a medium term to short term rental.

It does have paid for solar so that keeps the utilities low.

You can also utilize the 5% down program on 2-4 units multiple times so that’s another strategy that you can repeat. 

My boss just decided to deny an applicant who has a Utility Collection (like Water, Electric, and gas), and I'm struggling with my criteria.Any Idea will do.....

They furnish it, pay the utilities and rent it out to people staying for a short time. 

Cashflow - You mention cashflow year 2 in the single family....Assuming 5% down and a 6.5% rate, your mortgage on a $400k house will be about $2400/mo...add in: taxes, insurance, maint / repair, vacancy, utilities (if any), etc. 

Verify if there are any outstanding violations or issues that need to be addressed.Financial Analysis: Review the property's financial records, including income statements, expense reports, tax assessments, and utility bills.
