Using Architectural and GC fees to satisfy part of "down" payment

[Ty Mar]

Hi BP,

I am a senior architect with 16 years of experience with high rise residential design. I gut rehabbed a couple properties (designed and built) with my own resources, but considering this route for investing further, can i include architectural design fees and GC fees as part of my down payment when seeking a loan for a buy-hold or fix and flip property? Are there any regulations controlling what services can or cannot be included in the down payment?Thanks.
