In a way, I am just trying to prevent myself from forgetting something small that is vital for my guest. 

I will give you ideas on how you can overcome the number 1 obstacle preventing you from acquiring apartment buildings.I have acquired over 1,000 apartment units (and I did it with no money and bad credit) and I shared how I did it, here on BP:Part 1 - https://www.biggerpockets.com/forums/55/topics/690349-from-bankruptcy-to-1-000-units-part-1-thru-the-dark-tunnelPart 2 - https://www.biggerpockets.com/forums/55/topics/692382-from-bankruptcy-to-1-000-units-part-2-rising-from-the-ruinsPart 3 - https://www.biggerpockets.com/forums/48/topics/695243-from-bankruptcy-to-1-000-units-part-3-how-to-build-an-empireWho wants to go first?

A real estate license is unnecessary for real estate investing.

Mostly I find the refinance LTV combined with the low refinance appraisals prevent me from extracting all of my investment.So if you choose to go OOS here is some advice: Familiarize your self with the 50% rule.

We've financed many properties in such a scenario and the rates were no different than when a property is owned personally.However, I do agree that a holding company is typically unnecessary overhead when first starting out, but that is dependent on your personal financial situation, marginal tax bracket, etc.  

The buyer asked for me to get a certificated and mold expert to take care of this issue .However i dont believe that it needs that much repair I have found a special paint to treat that and prevents it from coming back.The property is in Philadelphia PA Is there any regulations of how bad thisnissue has to he inorder for us to treat it professionally.

There's a surprising lack of cars, folks use uber, mass transit but this is working in suburban settings when the house has space from neighbors and parking...Like tiny homes (which cost too much to address low income housing) renting out rooms is a zoning and locale acceptance issue that has only just started.FWIW to run a DIY rooming house you have to learn the tricks of screening, to prevent riots in the home, handle arguments, over night guests, dogs/pets etc etc.   

Setting up legal structures that were completely unnecessary for someone with one property. 5.

(ive heard there can be weird HUD rules with this that can prevent you from getting market value, but I could be wrong) Are they using short term loans with higher rates for a few months then flipping over to conventional?
