You should determine the monthly cost for property taxes, insurance, repairs/maint, capex & maybe vacancy.

If you have a fixed rate amortizing loan, your mortgage payment stays the same from year to year, but property taxes and property insurance premiums tend to increase. 

Hello everyone, I currently have 6 properties all in Maine and all insured through Allstate. 5 are landlord policies (3 unit, 4 unit, 3 unit, sfh and 3 unit) and one is home owner (4 unit).

The insurance company put tenants up in a hotel.

This will now make it much easier for agents and brokers to share and maintain information so cap rates in the area will become more transparent to realtors.As of right now your best bet on getting cap rates for particular property types is by contacting commercial brokers or commercial lenders.

@Ryan Keenan Lenders will generally add mortgage, interest, insurance, property taxes and depreciation back into your gross income when comparing it to your federal taxes and total PITI. 

People love me because I'm always 100% transparent and you should be in this message as well.So, in this instance, I'd simply say:"Hey there, I have a property coming up at 222 Rogers Ct and I'm thinking of managing it myself but I know I will need more help in the future as my portfolio grows. 

@Omar Khan ok I think I understand... so FHA always pay mortgage insurance premium unless you refinance.

However it is an investment that may require you to be more hands on to insure the decisions made affect your return in a positive way .  

If you don't have 20%, you'd pay  private mortgage insurance.
