My initial thought is to have her fill out the proper application paperwork and sit down with her to communicate the transition.

This is my understanding of the situation: sex offenders are not a protected class, however fair housing rules prohibit blanket denials of applicants based on criminal record because protected classes have been disproportionately impacted by systemic injustices in the legal system.

One feature I really liked is the application to e-lease option which basically automates the lease and move-in sheet once you get your tenants application based on the forms they fill out. 

However, you could also hire a handyman whenever something breaks, and have the applicants show the property themselves by giving the code to a lockbox. 

Lease, application, payment history, and other Tenant documents2.

What I say is "Hello, my name is <blank>, I have an application from Jane Smith to rent my property.

I got the drawings done and submitted the permit application and the city came back saying the property is in a flood plain area and I will need to get a survey done to go over next steps which is ($7k plus).

I listed it myself and did all marketing, showings, collected applications and did the screening myself etc.  

I have 3 applicants I would be happy to choose from and so far just have their application with background/credit check and employment, etc.Do I accept one applicant and then ask for proof of income, or do I ask all 3 for proof of income and then choose?

There are costs associated with purchasing properties such as earnest money deposits, option fees (if applicable), closing costs, deposits for contractors and utilities, etc.
