I've been surprised at properties that have passed conventional financing though...and even FHA....also, one could present 2 offers to seller--one for a cash offer and one for seller financing (at a higher price of course). 

design one for yourself. think about your market. like in columbus we have infill lots at 30x120 and so we developed and designed a house for ourselves. we build the same house and continue to Make modifications. it's the only new build we offer to build for clients. that's just my opinion. architects we didn't even use we looked at national builder Floorplans and decided. our typical lot is 3000-4000 square feet that we build on 

This is one of those, as is the neighboring properties (all of which operate as duplexes, though officially are noted as SF).

Are security deposits needed in addition to damage waiver, or do you pick one or the other?  

Should I add one or two more? 

One key piece of advice is to make sure to build strong team around you.

haven't been able to get one yet. 

That's a mine field no one on here is qualified to answer. ;) But your rental is doing well.

However, our current hard money lender only funds one loan at a time, limiting our ability to take on multiple deals simultaneously.
