Can someone please clarify this for me - if I take out a HELOC on my primary residence to purchase an investment property would that have to be for 100% of the cost of the investment property or can I just take out enough for a down payment? 

Many of my investor clients have purchased in MI over the past year. 

Purchase price: $210,000 Cash invested: $21,000 2/2 condo, in a 314-unit complex. 1.7 miles from the beach, great location.

Make small purchases and pay off the balance in full each month.8.

That agent was now on that purchase contract and he later sold the house about 4 months later and was on that sale. 

A cost segregation study was performed on this single family home in Fort Worth, TX purchased in 2023 with a depreciable cost basis of $272,633.

A good friend of mine told me he started a company to purchase and manage surgical centers.  

Table funding would essentially be purchasing the note from the note originator at the closing table.

If I do make the purchase for a house now, can I sell it in the near future or am I stuck with it?

I need to sell to investor at 75% of ARV (Purchase price+rehab) in this particular area. 2.
