I am not sure if thats true.

Set up purchase criteria that will define success for you, an arbitrary minimum purchase price is not a great criteria, instead I would use something like proximity to good schools, neighborhood improvement trends, etc.Finding good deals is really tough right now so it is important to have criteria that are solidly grounded and based on reasons that will steer you toward profits.

The coolest thing about seller financing is that you can create the terms you want (in reason) to the offer. 

The numbers look reasonable for the area, but I would love to get some advice on hidden costs and what numbers to research (aside from reno cost) before putting in an offer. 

The reason you should do this is because any business has an operating agreement and articles of the owner that are all public information.

However, on bigger pockets I had to put East Cleveland for some reason.

That would be the reason to pull it out; if I were to do it over again I would have pulled the money out of my IRA and purchased it directly.Thanks,-Bryce

There are also more regulations in CA, if you want to stay there for your first property, which is another reason I mentioned looking in another state and thinking about long distance real estate investing. 

Tenant “Y” has a 590, 3.2X rent, but just started a new job a week before applying and I did not feel comfortable renting to them for that reason.   

So if one can buy dirt at a reasonable price get it approved and built and filled up as stated above they will force equity and have a very good investment that is worth a ton more when completed etc. the issue out this way is finding any dirt you can actually build a park on  most cities wont allow them then you have the other barriers to developement and absorption like I mentioned above these all factor into it.. out in the mid west and deep south one can buy a park for 7 to 10 cap all day long.. in OR WA CA your going to find it difficult to find a park above a 4 to 5 cap.
