Cody,If you want to work with a bank or lender to build on a piece of vacant land you will need to be on title of the land for at least 6 months.

Does anyone have much success buying SFH with seller financing? 

Seller financing can be a fantastic way to get into a 4+ unit property, especially in a competitive market like Chicago.Have you started reaching out to owners directly or networking with agents who specialize in multifamily properties?

Note the property tax will be -10% on the rent by itself.Month 0 to 24: $2450 * 0.5 - $1573 =-$348/monthMonth 24 to 60: $2450 * 0.5 - $1541 =-$316/monthNext issue is due to the low leverage starting at month 24, the ROI takes a beating.  

I could be wrong or out of line, but I feel like this is a field where you really need some good expertise/experience to know how to address the variety of crazy situations that will come up.

@Jorge Vazquez we stopped doing signs over 10 years ago.We had a separate phone number on our signs, so were able to track traffic & applications from them.We were getting more & BETTER leads from our online ads then the signs - so an easy choice to stop using them (also time & money savings).

Quote from @Pierre Tran: Hi everyone, first ever post on BiggerPockets!

I would suggest reaching out to owners of multi family who have no loan on the property.

If they are available online or in person.

I've been surprised at properties that have passed conventional financing though...and even FHA....also, one could present 2 offers to seller--one for a cash offer and one for seller financing (at a higher price of course).
