LTV Financing

[Jeffery Lockwood]

Greetings,
This is my first post to BP. I have been following for months and have learned a ton. I have a question on LTV loans when buying real estate for long term hold. I have pre-approval from my banker on funding for investing. I have found a property that is actually a set of 4 houses and a duplex for 275K. they comp at 384K from 3 separate agents i work with. The properties all have tenant and cash flow for approximately 125/month per unit. My question is if I am taking a loan on these properties can I get a full financing option. I am buying these for less than the 80% LTV. Will I still be required to put 20% down or is the LTV based on the transaction and not the appraisal? Thanks in advance
