I have a home under contract that's in pre-foreclosure with no equity and the seller is upside down.

It is FSBo, but he will not carry the contract, or so the ad says.

I am now in a contract position as 1099 and have the option to fund my own Solo 401k up to 55k, which is amazingly awesome compared to most employers just providing the individual limit. 

Space program, military, military contracting.

Since the flood, I have rehabbed my home and we are two months away from finishing up a contract of rehabbing 135 units that flooded.

Buy and hold, house flipping, wholesaling, small multi-family, lease options, land contracts, large multi-family, assisted living facilities, vacation rentals, corporate rentals, self storage, notes, mobile home parks, medical office buildings, turn key rentals, etc.Is your head spinning yet?

Should I let the seller know in advance (before we sign a contract) that I will be assigning the lease option to a tenant buyer for a fee?

They just drop rent, contracts, applications, etc. right in there for me.

The properties I have been getting from my realtors are getting under contract at a velocity that is making my head spin!

Once a contract is executed you don't want to consider having to quickly switch to another lender.
