Mainly my mom who owns her own landscape supply business that I have worked at my whole life.

Expansion could have occurred and the floor contracted, otherwise you get a bowing effect in expansion and damage to the lap/T&G. 

I guess this means it doesn't include any of the surrounding landscaping/parking lot. 

Intelligent investors move money from one great market to another great market to capitalize on market movements (selling at peak in one market, buying at expansion in another).

I started talking to bankers with a 6 month time frame in mind and it paid dividends because it instantly showed I had a long term mind set.I am assuming that at this point you have some decent equity in all these homes and therefore could maybe use that to finance your expansion.

For those who are wondering, I did get the appropriate permits from the city for my work.I have not done any landscaping at this point, nor have I painted the exterior of the building. 

@Eric Baum You will need to go to the Planning Department and find out what the minimum lot size is in the neighborhood, what would be required to split, setbacks required for curb, gutter, sidewalk, landscaping, etc.

Landscaper, to install the drain system for the backyard of the house.Any recommendation will be highly appreciated.Emma Chen

I own a small landscape company and have been doing it for around 25 years now and also am a certified home inspector for close to 5 years. 

Also, in the spreadsheet, do you generally see or recommend having groups of property by life for the year placed in service, for example 27.5 year row for the residence in year 1, 5 year row for a dishwasher and fridge in year 1, and 15 year row for landscaping?
