In the very first section of Utah's terrific Buyer Due Diligence Checklist it states "Buyer is also advised to make inquiry at the local building department to determine if building permits and final inspections were obtained for any remodel work at the Property, if applicable."

Another option would be to call the employer if it hasn’t been too long since the application.

Murphy, 478 Mass. 664 (2018)A reverse mortgage did not contain the formal language of "statutory power of sale," but only said that the company could “invoke the power of sale and other remedies permitted by applicable law."

I was wondering if the seller would make anything available like their DTI ratio at the time of application or something?

This would disqualify them from the initial screening of applicants.

Personally I NEVER touch my cashflow and it has saved me numerous times when the tenant has moved out or when someone left their lease early. 

Have them pay for an application?

CC&R's and rules do state clearly board needs to inspect and accept any application for ANY improvements. 

Advertise it for at least that.Gauge the number of applicants.

I've got one SFR in Fort Collins, CO with the same tenants for the past 4 years (they just signed another year lease) and one townhome in New Castle, CO (turned over two months ago and people were knocking down the door for an application).
