You simply stack and bolt together the rings to the height you want.

Also I would talk with those that install systems they usually have a good feel for areas and maybe will do an onsite inspection.for me if just vacant land and all i need to do is dig a 3 foot hole to get soil samples I am going to just do that. 

The statement above simply doesn't make any sense.

If I pay it off, I could maximize cash flow earlier, reducing financial stress and allowing me to focus on other ventures or simply enjoy life more.On the other hand, I know some people advocate for keeping cheap debt and using the extra cash to invest elsewhere for potentially higher returns.Why I’m leaning toward paying it off:Security: No debt = peace of mind.Financial freedom earlier: A fully paid-off rental would give me a significant monthly cash flow?

I think it’s a more recent consideration (maybe in the past decade or so based on my digging / anecdotal feedback) and perhaps some of you that have been in the business longer and simply renewing old policies may be getting a pass.  

I would get together with your realtor, have them tour your property and then run comps to see what the value add would be, then simply pencil it out to determine the return. 

If this is simply you not wanting to accept partial payments and the rent is current, stop accepting it - and send a Lease Violation/Notice of Quit for Non-Payment of Rent - and force the full rent to be paid per the lease or start eviction.  

they said around 90% of market value.I tried to get them to understand that this property needs a LOT of work, almost a full gut, some holes in walls (small) old carpet needs to be ripped up, i mean like the works on this thing, you can prob get away with touching up the kitchen since its real hardwood and the bathrooms as well but this prop needs at least 80k.Found out owner actually owes 140k on property, and zillow is zestimating it to be 127k.

On the other hand, I’m hesitant to simply pay down more of a property, as we don’t need the immediate cash flow.Fortunately, both my wife’s job and mine are recession-proof, which allows us to be a bit more aggressive with our investments.I’d really appreciate advice from investors who have experience with frequent moves or military service.

Business owners won't want to get tied up in litigation and if there is a good chance they will lose, it is easier to simply follow the contract.How would that work with a lower-end tenant?
