I'm just telling what people DO here in Texas.And for the 50+ WeBuyHouses.com licensees (markets) for whom we do advertising across these United States, there are only a few of states with overly-stringent requirements for advertising - such as Ohio and to a lesser degree Florida and California.  

The cost of water and electricity varies drastically around the country depending on the area and provider.

Day 2 - Just put the roof up in around 80 degree heat, lickety-split!

Count on paying occupancy taxes (which vary), income taxes, and perhaps licensing and inspection fees - that would be the simplest advice I can give you.

This would, of course, vary based on scale.  

Have been looking for better job options,  however,  with a lot of degrees, and no work experience no one wants to hire.  

Then charge for advertising (cost will vary a bit but typically not more than $100) when filling a vacancy. 

Regarding interest rates - again, this would vary from lender to lender, the same HML I know has some programs that are below 8%.

The time limits on that vary on a lot of factors, one of the most important factors is if the person is a family member. 

i remember when i got my first home i was only 1 yr after grad so they accepted a copy of my degree diploma instead of the 2nd year of continuous employment .it was weird having to scan and fax that huge thing to the lender!
