"the typical home warranty costs $450 annually, and only 25% of premiums are paid to homeowners.

If you have a good FICO, a decent down payment and closing costs, go ahead an do the first one. 

Or are you planning to put 100% of the risk/cost of vacancies, furnishings and tenant nonpayment on the owner with you having 0% risk?

The cost is the same for a roof on a house that rents for $800 per month is the same as on that rents for $1800. 

I would guess an older home might be more cost to insure?

With fluctuating interest rates, tighter lending criteria, and increased competition for properties, securing the right financing has become a key factor in closing deals and maximizing ROI.Are you exploring creative options like BRRRR, partnerships, or seller financing?

Sometimes, buying an existing property can be more cost-effective and less time-consuming and maybe require slightly less permits, etc. 

I am looking to buy a property in SLC Utah that i would want to try and run as a STR to help offset the cost.

@Cameron Porter ultimately the most important part is the ARV, inclusive of the expected rehab costs.

It costs me $1,500 to evict a tenant with it usually taking two-three months.
