For debt service, I would use at least conservative 75 LTV(25 down) 6% IR a 25 amortization for multifamily on a conventional term to get an understanding of cash flow after debt and calculate cash on cash. 30-year amortization is likely but it depends on the location and it's a case by case.

You will need 20% down for a standard conventional loan.

Conventional Loan?

Also isn't the refinance loan generally financed at a higher percentage than a conventional mortgage?

I have a client interested in purchasing a fixer but has too much credit out to qualify for a conventional loan. 

Here are the Caveats though, you can only refinance to get the amount of your acquisition cost back out + roll in refinance closing costs up to 75% LTV on a non-owner occupied property and or up to 80% on an owner occupied property.If you want cash out beyond the acquisition costs, based on a higher appraised value, you must be on title for 6 months and you can do 75% LTV on a rental, and 80% on an owner occupied for conventional loans.You can do cash out on some portfolio loans immediately after purchase to as long as 6 months after purchase.

The biggest concern would be how you go from a bridge loan (hard money or otherwise), to a long term fully amortized conventional loan.

I'd just do conventional financing on a property in a location I want to live in that works for hacking such as a duplex or a place with an in-law suite.  

FHA is the 3.5% down program, and conventional is the 5% down program. 2) You have to live in the property for one year from the date of the closing.
