If you don't keep insurance on the property if its mortgaged, the bank will get insurance for you and you won't have a choice in the matter.

Lots of people fear the increased insurance premiums, expense and hassle.As to the costs, just talk with a local pool company.  

Private Mortgage Insurance is simply an insurance company insuring a portion of the mortgage.

I actually bought a 4 unit a mile away for $45,000 last year but that needed about 30K worth of work so I feel this is about right as this one is turn key with no repairs needed.The seller financing deal - Sales price $63,500Cash at close from me $50004 year note @ 4% for remainder ($58,500), monthly payment of $1000 with balloon at the end, no prepayment penalties.Monthly projectionsIncome =     $2200Expense=    $220 management                     $220 CAPEX = No problems yet but "Unknown age" on the roof and owner has had property for 20 years                     $480 Insurance/taxes = Total taxes for 2017 were $4982 on assessed value of $78000 plus $600 a year for insurance

The current lender is an insurance company, and I'm not sure how hard they are to deal with. 

You'll need to get title insurance.

Most of the good cash-flowing properties that we are seeing For 15-30k down that will cash flow on average $150-350 /mo after "The Big 6" (mortgage, taxes, insurance, vacancy, management, maintenance) have been paid.

That could have insurance and other liability implications as well. 

I’ve got the age old question of whether we should sell our townhome or keep it and make it our first rental.This is my first post on BiggerPockets so please let me know if I have left out any information that may be helpful in the analysis.Single Family TownhomeBuilt: 2001Purchase Date: 2008Purchase Price: $270,000Property Tax: $5700/yearHOA: $125/monthWater/Sewer: $1320/year (Must be paid to county by home owner)Insurance: $800/yearMaintenance Costs: $400/year Other planned future costs: Roof (in about 5 years, ~$5000), water heater (in 7 years, ~$1300 including labor), water softener (in 5 years, $500)Current Mortgage (Refinanced in 2012)Term: 15Rate: 3.375%Principal: $140,000Market Value: $230,000 (Upstate NY market with minimal appreciation expected)Rental: $2000/month ($2200 possible but I want to be conservative)I was also considering refinancing to a 30 year mortgage to help with cash flow but I’m not sure if it is worth the $4000-5000 in closing costs to refinance.Normally I would not consider this a good rental property because of the low/negative cash flow.

I sold insurance door-to-door in lowell 2008-2010 and did extremely well.
