You could setup a simple waterfall structure where the normal split is 70/30 and anything over a 10% CoC is split 50/50.

Offer what's normal for closing costs.

But, normally, the thought among lenders and banks is "we don't have to be the lowest we COULD be, we just gotta beat the other guy." 

Both of these would normally get factored into escrow, but if applicable you’ll be responsible for paying them out of pocket Last note-even if the seller requires a down payment, you have other options.

Is it normal for my general contractor to push the cost of his general liability and workers' comp onto me (the owner/investor) at the price of $2,600? 

If your someplace that has harsh winters, frozen pipes can be a nightmare for mobile homes so I would suggest checking the insulation underneath etc...I think the main difference is that mobile homes tend not to be as durable as a normal sf stick built home so your ongoing maintenance and repairs are usually higher.

This costs about $75 per month, or, if I can get one of the tenants to allow me to set up my "Automation Hub" (I use Smartthings HUB in my setup), I will give the tenant $25 per month towards their bill.There are many ways that Smart Devices can help, not only in the case of smoke detectors.I have motion detectors which turn on and off lights, cameras that record to the Internet, leak detectors that tell me if there are problems with my basement, particularly if one of my equipment like a Hot Water Heater or Hot Water boiler is leaking, etc.In fact, I normally buy properties in transitioning neighborhoods, capturing the appreciation as the neighborhood gets better.The Internet Cameras became very important in this situation for 2 reasons:1) I kept getting sanitation tickets for dirty sidewalks.

When water has been off for a while and then turned back on, the deposits may prevent water from flowing at normal velocity.

The way I do calculations is I need my properties to rent for 7 days a month (approx 85 days a year) at normal rates to pay all bills and repairs/capex.

The fact that as an agent you must constantly prospect new people and communicate with your sphere of friends, family, coworkers to grow your business is an unintended benefit.I've been very suprised to learn who else is into investing, buying or selling just by reaching out to my sphere during normal prospecting.
