I am wondering is it possible to secure at least 2 homes with this money and if so do I need to start an LLC first to put them under so it wont effect my credit score even though it is a 750 and also to keep it from coming back to haunt me in the future when do try to buy my own first house to live in.

Not sure if you can do this or how the set up is but generally the noise (stomping, running, house shaking) in many places tends to travel down more noticably than up.I would think any soundproofing options would be costly and possibly not as effective as necessary.

Maybe you should buy a property instead.verb (used with object)to be of use or value to; profit; advantage:  All our efforts availed us little in trying to effect a change.

On my leases, I have wording that says something to the effect, “if this lease expires, tenant may stay on a month to month basis but still subject to the terms of the lease until such time a new lease is signed.”

Is the transaction once removed, meaning I personally want to buy the house (I'm not making money off of the purchase of the house, but the remodeling done).

The transactions should be:Investor -> Wholesaler -> SellerBut my contract I had wasInvestor -> Seller To try and compensate he then sent me a copy of an assignment which I refuse to sign since he needs it signed by the seller.

You need both for wholesale transactions unless you are doing a double close.

,I purchased my first single-family home last year using the VA loan, i am doing house hacking, however, i am thinking about refinancing, however, i could not find a clear answer on how that would affect me when i am trying to buy another property or if it even has any effect at all. 

Using good debt properly and effectively is mission-critical!

Initially I thought about getting a hard money loan and doing a traditional transaction so that my in laws can get their money right away, however time is not of the essence Someone also told that me to save money (avoId poInts/fees/Interest) and just “partner up” with my InLaws and write a contract stating that upon the sale of their house, they’ll get their 400K and I’ll get the rest, have them give me a quitclaim deed to the property and i’ll pay their mortgage and expenses during the rehab months.
