So instead of paying the bank for a home equity line of credit on my first home and paying them interest, I was able to use a personal loan to myself via my employer 403b and pay myself back with interest. 

My personal and professional experience has been that they do not provide actual replacement costs in their evaluations. 

I got quoted $1490 yearly cost plus a $30/mo retainer to have unlimited access to my personal real estate accountant.  

Just a FYI you don't need an LLC to do RE investing. if you are looking for the checkbook control then yes you will need one, make sure the custodian you choose explains the prohibited transactions and disqualified person list to you. 

I've personally worked with a handful of "investor-friendly" lenders, primarily on DSCR loans in recent years, and each time I've run into significant delays, lack of transparency about the process, have been fed the requirements in a piecemeal fashion (every few days there's a new random request rather than having it all organized from the start), and have even run into lenders who were substantially misinformed about the real estate industry or the laws that govern it on both a local and federal level.I think there should be a better site to encourage accountability by tracking how long it actually takes each lender to close their loans on average, and what unexpected hurdles investors encounter when trying to work with them.I can't seem to find such a site.

They have a more modern view the marketplace than some of the other, more traditional outfits like MDS.When I was active in senior housing, I was the in-house feasibility study point person doing both the forensic analysis of the market and competition ultimately making the recommendation for go/no-go on a project.

You seem like a very intelligent and hardworking person; I'm sure you can come up with a value proposition that is unique to you. 

B grade property walks are attended by my children to run around and tell me which bedrooms they would pick if it was their home.43605, 43608, 43609 are the popular zipcodes for bottom-budget value purchases...I manage a ton in these areas and my personal portfolio contained over 40 43608 properties at the peak. 20% of these properties will be crazy money earners, 20% will be astounding money pits, and 60% will fare average.I have evolved into the nicer 43612/43613 for my personal portfolio and find the properties earn consistently and far smoother than my 43608 houses. ($80k renting for $1200 vs $40k renting for $800 multiplied by the ratio above vs boring consistency of the nicer area) Oh and I have zero excitement for apartments.

I share this not to discourage you from embarking on this project with you as a manager, but I flip homes and have seen for myself the incredible savings in time and money that can be activated when you have the right person overseeing the project and who has the relationships with the subs that can make sure to push them and hold them accountable.

Lots of things done 100 years ago are "up to code" because 100 years ago when they were built that was the building standard and that is the standard they need to meet UNLESS you touch it.
