one option is to continue renting out all four properties to cover mortgage payments and generate passive income.

I have nothing against me, no criminal record, good credit, job, income, savings, single male, no kids... could the HOA decline my highest offer the property to whoever they choose? 

By selling the property now, you can avoid the time, money, and effort required to make repairs and potentially deal with ongoing property management responsibilities.On the other hand, if you are willing to invest in the repairs and potentially hand off the property to a property management company, you may be able to increase the value of the building and generate higher rental income in the long run.

@Gordon Middleton usually only $300-$400 annually in Michigan.

If the bank pays your property taxes on your behalf (ie they are added onto the mortgage payments), then yes the amount may change annually if your property taxes go up.go to the bank by yourself and take notes and ask questions. 

Will need to increase income or decrease debt (or both) for a more favorable DTI. 

House #1 is rented out - tenant met all the requirements (income 3x the rent, over 600+ credit score, no evictions) when the PM screened rental applicants.

I have good credit and a stable income, but not a lot of savings.

Breaking these three down on the direct impact they have had on multifamily pricing: rising interest rates impact your cost of capital, and taxes and insurance impact your net operating income (NOI) which has a multiple effect on evaluations when using the NOI approach for assessing value.Value, while a simple definition, is a complex concept.

How do people then generate a monthly rental income?
