I am planning to build a business to replace my income in couple of years so as to have monthly cash flow equal to my W2 income.

Just saw a well respected MF operator buy a property they have big plans for in a very rough neighborhood. 

Main questions should ask about the seller's:- Reasons/Motivations for wanting to sell- Desired timeline to close- Plan's after selling (relocation, reinvesting proceeds, 1031 exchange, etc)- Back-up plan in case they are unable to sell within the desired timeline- Reasons for not already selling to/with a investor or RealtorAdditional questions will depend on the type of seller lead i.e. pre-foreclosure, probate, fsbo, absentee owner, etc.Here is an example of a youtube search you can use to begin finding call recordings.There are 1,000s and you'll find that the best/most effective ones don't even sound like sales calls.

If you need financial help, ask under the "Finance, Tax, and Legal" forum.

My advice would be to put together a solid plan.

We recently did a loan involving a borrower with a mind-numbing operating agreement involving nested LLCs, retirement plans, and individuals. 

I plan to raze a house I own in SD county and build a quadplex on this one parcel. 

So I always try to plan ahead, triple check my due diligence, and be VERY conservative with my underwriting.

I will spend around $5000 - $7000 a year for tax planning and filing.

hey @Matthew Toporowski, at the least I would check their financials/tax returns to see how profitable they are (which translates into how easy it will be to pay your rent).
