@Dwayne Hunter can you elaborate more on income, expenses and purchase price on what you believe you will clear $300 on?  

I could certainly elaborate more, however I will get to the point.

Could you elaborate on this please?

Could you elaborate a bit more?

I am unsure of the nature of your problem with the rentals as to why you are not making money, so please elaborate if feedback is sought. 

Hi Jared, thank you for responding. if you dont mind could you elaborate on a construction line of credit and how it works?

Can you elaborate on what you consider a good return in today's market?

I will either give you SKUs or better yet when writing your proposal if you aren't given that initially give your own list of those with a "Or others of similar type and quality at costumers request" so if they like what you picked they sign off or know what you budgeted if they don't, so they either pick similar or know they will have to pay more if they want higher end.After a couple of jobs with the same guy hopefully the investor will be "Use the same stuff we did at 123 Main for the fixtures but do the counters from 321 Center" so you cut down on time hashing that out.I do agree with others that INITIALLY giving good references, letting me walk a current job site, and seeing a portfolio of work as well as being able to provide copies of the license insurance and other pertinent info will show professionalism.
