@Dennis GallagherIt's my understanding that the "Income-Expense Ratio" primarily use operating expenses as the expense variable, which includes costs like utilities, property taxes, insurance, maintenance, repairs, property management fees, and trash removal, all of which are considered when calculating a property's operating expense ratio (OER).You calculate OER by dividing the total operating expenses by the gross operating income of a property.

Invest in a security camera—we had a break-in where someone lived in the house for days and stole appliances, which insurance didn’t cover.

I recently watched a BiggerPockets podcast on YouTube where both folks made flood insurance mistakes from not noticing something in the disclosure.

Gas going to be closer to 5/gallon than 4... car insurance probably 150 or so.

I have taken all my taxes and insurance out of escrow, and I run them through credit cards to rack up points, so I pay a lot of bills every year.3.

Lastly, make sure your tenants have renters insurance to cover their property.

So just curious if my number formula is correct $15k down plus $15k Reno = $30k rental income/year  $14500 vacancy rate 2% operating expensive 35% ( to cover condo fees maintenance insurance ect) $5500 a year mortgage so roughly a 12.25% cash on cash return ? 

Beware with manufactured homes, as getting lending as well as insurance is tricky!

Your current home would rent for $1800 and PITI (principal, interest, taxes, and insurance) is $1250.

I do not have a lender right now, and I will need the 12-month rent history as well as various metrics on the property such as insurance quote (which needs property information in order to obtain), existing debt, and purchase price (which would be established while making offers).
