Reading/writing/meditation has its place.making the calls/offers/arranging financing etc is another component

The max contribution for Solo 401(k) plan is consists of salary deferral of $17,500 (plus additional $5,500 if you are over 50 years of age) + profit sharing component of 20-25% of the compensation (depending on business structure).

The class of tenant in the 500 a month rental is usually more work and the areas tend to be not as upscale in nature.When the rental is lower the management usually wants a higher fee.The other component is do you have the aptitude to want to be a property manager and manage yourself.

The true solution will NOT have ANY component like the prebate.

I broke up the process in to the major components.

For example, while the HVAC system may have a couple more years left on it, if a buyer is trying to decide between your house and a competitor, and the major difference is that the competitor's house has no deferred maintenance and yours does, he'll likely go with your competitor's house.On the other hand, if your hand is much nicer than any competing house in the neighborhood at the same price (and is also priced well), you may not have to fixed stuff like the HVAC system to get a sale.In other words, without having big picture about what you're trying to do with the house and what the competition looks like, it's impossible to recommend whether you should replace old (but working) components of the property.

They still control all the components (the deeds) that would pose any risk to their title insurance.This seems to me to be an issue of fear and not fact.

And unlike so many "products" discussed on here, incredibly feasible without features that are detrimental to the borrower. 

You will need to learn all of these components of a development deal: land acquisition, site selection and sourcing, zoning and entitlements, architectural design management, deal underwriting, financing, construction, leasing, property management, and sale or asset management. 

That will tell you how many units you can build on the site.Next, do a full underwriting or proforma analysis of the project, of which the build costs, are one component in the model.
