I’m trying to buy a house in Phoenix using a second home loan, putting 10% down.I'm trying to understand why anyone would choose the 2/1 buydown if you end up paying the same amount of money, whether you select the 2/1 buydown option or not.

Go to your local REIA and see if there are any subject matter experts in your area that teach classes or give presentations.Even when the statewide statutes are the same, they often get implemented in different ways locally, so the national courses tend to be just junk.If you are determined to spend money on a course see if you can buy off ebay or alibris or FB marketplace.Lots of misinformation on tax lien/deed investing.

Unless the deal is half off the actual value, why would you buy into squatters?

My question is, how does the process then become for buying properties in your state LLCs?

Think long term, delay gratification, and buy the property you want to own the most 10 years from now.

I recently purchased my first investment property, a duplex, and am eventually planning on buying more when the time is right.

In it’s most basic definition Buy - Purchase a propertyRehab - Value-add with renovations and rehab things that need to be fixedRent - Find tenants to pay your mortgage (and maybe some cash flow)Refinance - Once the property’s value appreciates from rehab and reappraises for more than you purchased it for plus renos, you can use that gained equity to do a cash out refi.

More chance of fraud ( There is always a new lender popping up with some crazy program and people fall for it and end up paying upfront fees, never to hear back from the lender) 3.

Look up Pace Morby and his groups, etc, they sometimes source homes that don't have as high of an entry fee as buying a home the normal way would.
