The house had been vacant for about a year as the previous tenant could no longer stay due to her age.

I have a ge real question that has been asked probably a million times on here, but I cant find a clear answer for my situation.

Obviously the size, age and condition of the home will change these figures significantly, but what should I use as a conservative baseline for these costs? 

Growing up in the construction industry, has allowed me to understand the building process from start to finish, managing builds and flips since age 18.

The following drive housing prices:Disposable income - very high right nowPopulation increase - many areas are experiencing large population growthInterest rates - still lowInnovative mortgage products - not the same as 2008 but still lots of flexibilityAccess to credit - credit markets are wide openMortgage backed securities - we are in the golden age of capital with huge demandHousing service providers - there are huge personal incentives to push transactionsFinancial literacy - this will always cause irrational decisionsOn a different note, I recommend talking about things that matter with people who care. 

The earth shifts and the age of the home have a lot to do with that.

Make sure everyone knows anyone in the place over the age of 18 needs to apply.Along with filling out the application have the applicants provide proof of income (copies of paystubs, etc) and a copy/picture of their state ID or drivers license.Once you have all of their applications and supporting docs then run their applications through a background check system that will give you their complete credit, criminal, and eviction history for each applicant.

I am considered unrealistic by my peers because they think being a millionaire by age 25 is crazy and retiring by 35 is even crazier.

In general they are a little less stringent on the onwer builders permits  than the contractor one.

How do people get away with such  blatant practices in this day and age?
