There is a national convention for the health care assoc I belong to the same time as this one. 

I was thinking maybe a SFR, which would put my PP at $350K, considering that would be a 5% down conventional loan which would put my payment at $2400 or so and considering market rents are around $2500 or more in that area it would make me a great investment.

also  consider a  conventional loan  as  these  loans dont have the preeminent   mtg ins that FHA loans do 

I'd thought about it but read that investing from an LLC precludes my first few deals from.taking advantage of lower rate lending for my first four or five deals as a private consumer using conventional personal financing.

There are some conditions you have have more than one, but generally unless you are moving around for your job, it is pretty difficult.You can have up to 10 Fannie or Freddie backed conventional mortgages.

It's very low if you're using conventional financing.

I understand how conventional loans work, but what can I expect for a new construction project while in development?

My role is to purchase the property through conventional finance and to provide the down payment. 

Choosing to go FHA vs Conventional is more important than most think.

Freddy/Fannie conventional loans want to see those 2 years.
