I'd also go by the home and post a notice of an inspection-you never know something could have happened to them (either they left, are sick).

Invested $170k since 2021 and total return of barely over $5k, which includes $2700 left from the first property they sold end of 2023(orig investment of 25K). 

Sometimes those properties exceed 100% expenses to rent they bring in.Generally though, when I look at my overall portfolio at the end of the year, the expenses usually are right about 50%.So, it's an important number to keep in mind but consider the specifics of the property you are looking at more than any 'rule of thumb' measurement.

Pre-approved at 6.5%.Well, you have your answer right there.

If your friend is going to find another tenant, they should let the original tenant and the voucher office know right away so that they can get back to looking.About half of my portfolio are voucher tenants at the moment.
