Check local law, whether you have to accept varies by state.

I'm currently looking to get into real estate, and I find house flipping and repairs an interesting category to get into.

Is this for all DCSR loans or can these items vary?

Does the market really want nearly uniform full-service brokerage service (often of varying quality)?

I’d put 60% returns in 55 days in the “too good to be true” category for sure.   

Yes it explicitly allowed things like the term and rate, and I wrote that it should exclude anything additional which is unnecessary since I couldn't be there to read the closing docs themselves (which I assume can vary depending on what the branch leader/loan officer wants for the nonconforming loan).  

You can file paperwork yourself or as others have stated, hire an attorney.Typically, you'll want to have a notarized affidavit filed or writ of possession issued and signed by a judge.This can vary from jurisdictions so if you are unfamiliar with how to move forward it may be best to consult legal counsel.Legal counsel will typically cost in the low thousands after filing fees, processing fees, attorney fees, court costs, etc.

On paper lay out your scaling and resource categories.

I personally have funded the same house 2 to 3 times in some markets each time landlord failed.. bank took It back new vendor bought it we financed the purchase and rehab and new buyer comes in.Or landlord sells to wholesaler for pennies on the dollar and I am funding the wholesalers end buyer.. these areas unless they gentrify if they stay rental and continue to add rentals.. just never go anywhere .. the only way they do is if rents sky  rocket and rents don't sky rocket in D and low C class they actually stay quite stable they follow HUD.. pricing by and large.. which of course varies by state , county , city. 

Development projects can vary from a 1-lot Single Family home to 20-acre subdivision, to a 4-acre commercial site, etc.
