single family or multifamily?  

Charge a fee for the ESA.

Small investor, looking to purchase one to two single family homes per year over the next 7-10 years? 

I charge a good bit for my properties, that screens them.Do hotels run background checks on guests?

Hey Jonathan - I usually start by checking what similar properties are charging in the area, considering things like size, amenities, and location.

Quote from @Edward James smith: Hello, I currently own a single family house with an ADU, and a duplex.

Do you think a duplex is generally a better investment than a single-family home for rental purposes?

The AMC charges a fee on top of the appraisers.

However, I haven't had a single application submitted for over two weeks.

My humble advice to anyone attempting to do creative finance is:Creative finance is for experienced investors who have access to capital if anything goes wrong.Learn the lawsDon't use a contract "off the internet", laws vary by state and are also regulated on a federal levelLearn the financing techniques correctlyDon’t skip parts of the processDon’t ever do a “kitchen table” closingUse the proper deedAn attorney can help you with the legal work, but the rest you are on your ownYour guru will not bail you out“Investing” in someone else’s deal by providing a small 2nd loan so the “investor” can pay for “cash to the seller” and for “closing costs” so he can do the deal is a very bad planKnow what problems can ariseLearn the responses and solutions to problems before they are neededKnow everything there is to know about Title and what that meansKnow who a "protected class" individual isLearn the "back doors"Learn human natureUnderstand timelinesUnderstand regulation enforcement (some of these "mistakes" have a 10 year statue of limitations ( they can charge you 10 years AFTER you do the transaction) and carry hefty fines and possible imprisonmentThe court doesn't accept "I didn't know" for an answer"Know that the source of the lead plays a serious role in some states and federallyKnow how much of a "profit" pushes the boundaries to invite an investigationYou can be sued by the seller if you don’t do things correctlyYou are automatically at fault if an investigator or attorney or regulator gets involved.
