As Ben mentioned, the labor is what's going to kill you on those old windows, labor and the fact that unless you have guys working for you that are real skilled at painting and glazing, they're probably not going to look "picture perfect" when they're done, either.

Experience, skills, etc. to show that you will be able to do the job, and make a profit.

I'm currently learning coding on my own so I can have a skill where I can relocate and still earn income while learning and becoming a real estate investor part-time like many of the BP podcast interview I've come across. 

Paper returns are ALWAYS better than in your jeans, there is a whole other skill set required to understand management, maintenance etc.

Through this site I hope to learn if my skill-sets are suited for this line of work, and if RE investing is compatible with my desired lifestyle.  

Art, that's something I was wondering about.

I know my market and feel that I have skills needed to take a stab at this on a larger scale.

Using a spray guard can be an art.

I find it may be some ego trip that is half-truth, but it might help some folks.I could care less if they have bad writing skills.

I added original art, designer furniture, and some nice sheets and stuff.
