Can I find an agency to help me build a business foundation and start to fill a pipeline working part-time in real estate over a 3 month period?

I may be able to help if you’re willing to partner for a short period.

I'm currently in the due diligence period for buying a house and fourplex on the same lot.

Period.

These include loan payments, taxes, insurance, utilities, lawn care, and any other costs that occur during the Rehab period up until the property is fully rented. 

As your primary residence, you should purchase the best house you can afford with your kids education and extra curricular activities in mind.Problem with SF public schools is the lottery system, but that's a whole other discussion.

However, when having discussions with them and their disregard for anyone that has been with them for a period of time, I was completely turned-off by their attitude.After I decided that we needed to look, I quickly noticed a couple of key differences:  accounting, modern interface and mobility. 

Having started my REI education about a year and a half ago after stumbling across BP podcasts as entertainment for my daily commute I am excited to finally take some action. 

I’m trying to crunch numbers to see what would be more valuable an investment over a 30 yr period.

After that said time period you can technically move out and keep the FHA loan.
