Is it recommended to start with a SFH or is it manageable to begin with a Multi unit home or complex? 

there are 3 or 4 companies that sell how to programs normally about 2k to 3k.. this will give you the basics.. or you can try to find a used set of books tapes on E bay for 50 bucks or so.

As a beginner, I’m still reading and listening to all the great advice and content out there, but tentatively working towards house hacking via a multi family property in Philadelphia.  

Fee simple lots provide greater flexibility than multifamily projects under one parcel.4) Kimberly Byrum - Lease-Up Rates by Asset Type:Garden Style Multifamily: 18 units per monthBTR Cottage Style: 12 units per monthBTR SFH Detached: 8 units per month5) John Jones (BBL Building) - Efficient and thoughtful design remains the best way to reduce costs.6) Tony Benge Margins are comparable between garden style multi-family & BTR, but BTR is in much higher demand.It was a great turnout, excited to see the BTR sector’s growth between now and next year’s event!

Hmmm that sounds even easier, I see home depot has a suction cup for 10 bucks, I'll give that a try first, thanks!

Routers can be crazy expensive for a high end one.I would look at best buy and read the reviews to find one that is the best bang for the buck without overpaying.

I Personally would go the multi family route.

For single-family and multi-family rentals - plan to put 20-25% down on investment properties.If you find a rental from 2-4 units with a month to month lease or a vacant unit that you could technically move into/would move into after buying within 60 days - plan to put 3.5-5% down. 

Looking for targeted courses on large multi-unit commercial/residential investing. 30-200 units. 

Won’t this be same as multi family duplex?
