A lot more detail is required for an accurate assessment.

Look at trends in property values, rental demand, vacancy rates, and economic indicators to assess which market aligns better with your investment objectives.Risk management: Determine how much risk is involved in each choice.

There  are both assessed values and tax sale values.  

unfortunately if the DSCR only principal interest taxes insurance and any applicable HOA or assessments 

the normal tax liability is based on the amount withdrawn prior to the 10% penalty being assessed.

Consider factors like location, market trends, and the condition of the building itself when assessing its value.

Activities such as appealing assessed values, shopping for cheaper utility providers, shopping for cheaper insurance, or even energy efficiency upgrades are all on the table.

More & more HOA's are going the foreclosure route to enforce their assessments.

Secondly, DSCR loans offer favorable terms and lower risks, as they assess the property's ability to generate sufficient income to cover debt obligations.

OP, you just need to get better at assessing the property’s condition during a showing.
