Army Veteran so I was fortunate not to have a lot of the typical expenses or a down payment.

Quote from @Anshuman Thakur: Can someone please shed some light on how- convert 401k to SD IRA- how to use SDIRA to buy properties- how much down payment is typically required if we are using SDiRA to only fund downpayment on a multifamily CRE, and which banks typically work with SDIRAs- how does LLC structure- property management and cash flow work in this situation?

Building departments, typically, are very helpful. 

As a lender, it is my firm belief that honesty, transparency and service are the most important factors.

A hands-off garage conversion ADU is over $100, even doing much of the work yourself, it will be much more expensive than your estimate.Single ADU additions in single family zoned areas are typically one of the worse re investments. 

Once you close on your property:- You need to get a Phila tax IDhttps://www.phila.gov/services/payments-assistance-taxes/tax...- Then you need to register for a commercial activity licensehttps://www.phila.gov/services/permits-violations-licenses/g...- Once you have a commerical activity license you can finally get your rental licensehttps://www.phila.gov/services/permits-violations-licenses/g...All of the above will be done using the eClipse online portal systemIf your property is built before 1978:The system will kick back your application and you will not be able to get a rental license until you get a Lead Safe test.This is when you will hire a licensed 3rd party to come out and doing a lead test for you.

@Stan MendozaRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

This was my second foray into real estate investing, the previous one being through a “full service” turnkey provider.

Members of these in-house capital markets teams typically have prior experience working at multifamily debt brokerages, investments sales shops, etc., and a full rolodex / database of lenders whom they have rapport with to boot.

Lenders typically require a resume for the GC involved in the borrower's project to assess their qualifications.When it comes to a GC getting funding for their own projects, while some lenders will take your experience as a GC or builder into consideration, most primarily look at your track record as a borrower on title when determining approval and pricing.That said, if a lender deems your experience sufficient, they may allow you to act as the primary GC on your own project instead of requiring you to hire a more experienced GC.
