My question is, if I was to proceed with the Subject To deal, will this somehow be discovered?

You can submit an offer but be prepared for a potential counteroffer.

That property was also supposed to be a few month flip, but I had to fire my contractor who I'd been working with on all my properties.

You look like the kind of person who is going somewhere.

Your current property must be leased out 2.

I recently seperated from active duty went guard and my partner who is active duty and I are trying to combine our VA entitlements as we did previously and co-signed on our previous loan.

With $50k down and a 7% rate, the payment would be around $3300.In the Denver area, you can get $800-$1000/room.

Effectively no, otherwise everyone would do it and there would be no rent controlled buildings.If the property becomes vacant there are scenarios you can remove it from rent control. 

From there we identify properties that could have some potential and if you are interesting in diving deeper, 1) we do a thorough video walkthrough to give you a realistic look of the property, 2) we give a ballpark estimate of rehab costs (we do 40 a year with our GCs o we will get pretty close), 3) we talk through market rent with our property management team, ARV, and potential highest and best use.Ideally you find great investor agents who know their market really well and have a network of resources to provide you with enough confidence to take reasonable action. 

ADU zone expansion is not certain, and even then who knows what the rules will be (owner-occupied requirement, etc).
