For example furnace, water heater and appliances all have limited life span.

The previous post (2 before mine) is an example of why you must be careful of who you accept advice from.

I see all over the internet a short answer of no, but what about the following situations:1) example: you invest 10k from IRA and 10k from personal bank account to purchase a property.

They seem like pure liabilities with no use.An example is here.  

Essentially is as follows:New Lease Fee (one month’s rent) + Expected Missed Rent + “Refresh” Cash(Refresh Cash = the amount out of pocket to prepare the property for new tenants, after tenant deposit is spent)It looks like this:(A/B)+(A*C / B)+(D/B)Where:A = New lease fee (1 month's rent) ($1,000)B = # of Months in lease (24)C = Expected # of months vacant in-between tenants (1.5)D = “Refresh” Cash ($500)In this example:($1,000/24) + ($1,000 * 1.5 / 24) + ($500/24)Which is:41.67 + 62.5 + 21 = $125    which is 13% of monthly rent in this scenarioThe equation allows me to make a judgement call in many different scenarios.

Where can I find a good contract example to use for purchasing the home?

For example, for the first couple of deals... you go find the house and then assist them with the renovation/flip and you share in part of the profits. 

It is a good example of what I call a “conforming property”.

The team building will just come as part of doing it, not something that needs to be done a year in advance (for example, now that I have need, I've been talking to lenders and met a great contractor, I'll also need an attorney in short order, so I'll be reaching out there too).

arbitraging bank loans to buy notes for example ?.
