Can't paint every deal with the same brush...that being said the typical strategy is lower payments = more cash flow.  

Brushed Nickel Frame (481-166) Lighting – Hampton Bay 3-light Brushed Nickel (610-563) Towel Bar Set – Greenwich 3-piece Bath Accessory Kit in Satin Nickel (690-977)

The brushes and grass is almost the height of the house.

My husbands aunt/uncle own a house worth over 800k and its less than 2,000 soft in Richmond section of dallas.

You'll need about 20% of the cost of the construction, soft costs, etc.  

And the only time you would be called on it is if someone complained or your in litigation over a construction defect.And with a Developers license you may NOT do any of the work your self.. from running a broom to a paint brush or hammer..

It is a soft wood and dents/scratches easily.

I am a landlord and need to have an addendum signed to extend the lease for only few month. Can I just get a signed copy by the tenant and I to be legally valid or do I need it signed in person?

You were a realtor so brush up on the current laws.

MLS, off market, wholesalers you name it and I will have competition.So with that said, If you are confident your repairs are $65k and the ARV is $620k, and you are comfortable with a $100k spread, bid appropriately.Using all of my soft costs, I think i could out bid you on that house.
