Assuming you're going to occupy the new property as you stated, you might qualify for low DP programs, which I believe have limits to the loan size (which one of the lenders here can probably tell us about).  

I come from multi family (MF) property ownership/management of a few properties of various sizes here in Los Angeles.

@Graham K.In this situation I would suggest still shopping the rate and costs for this size of loan.

Ask the standard questions: age of the home, size of the home and lot, number of beds, baths, is there a garage (attached or detached), any recent renos (were they inspected or permitted), how much of the space is finished, etc.

I also do sales and marketing for a moderate sized furniture manufacturer which allows me to travel between the Syracuse and Buffalo, NY areas at least 4 times a month. 

How big is the loan size?

Tenants can mostly rent units via the software now, but I do have a property where it doesn't make sense to put in the automation because of the property size.

I used the comps from the appraisal and I'm nicer then then the 700 place and if I put in new flooring about $2000 I would match the 908 units in the area my sample size is 4 propertys.

Search "proportions" and/or "similar figures" and/or "indirect measurement").This will help you figure out how many/which sized cabinets and appliances you can fit.

As for the size, you will need see what your market needs and what you can afford to build.
