New landlord question- if I have an individual who wants to rent my place for their parent - who do I have fill out the application?  

I have searched and filled out endless online forms only to have lenders offer me unsecured loans or other products, but not a heloc.  

I personally send a spreadsheet to my clients and have them fill it out. 

On a pre-1900 build I often see them filled with mortar, at least here in Milwaukee.

I filled out their survey and provided some constructive feedback, even though I don't own a STR here.

Even if they couldnt offer the service to complete the form i would expect them to make me aware i needed to fill it out in the first 90 days as i am finding out now.

After I fill the last vacancy, the building will generate as much cash flow in one month as its predecessor would have generated in a year.There are so many other stories whose origins are with that same knock on the door, but this one's already long enough.

As you know, marketing and price are both very important, and vacancy will significantly impact your income, so you are almost always better off charging a lower price and getting it filled with a good tenant.  

Maybe the P trap under the sink is not filling with water correctly and allowing sewer gas to come back in.  

I'd start with filling out your profile here a bit more- we can't tell what market you are in.
