This is going to depend a lot on what your capacity is, capability is, cash is etc. Its a broad question. What deal size are you looking at ? 10 lots is going to be different than 100 lots. A 500 k deal is going to be different than a 5M deal.
I think if there is a little insight into what you are looking for specifically in terms of deal size, it would give you a better response.
Also, on the second part of your questions, i will depend on what you are looking for. Are you looking for a value add deal? Are you fine with a stable investment on the front end that appears stable going forward?
Are you in a good market with a lot of parks locally that local is an option?
With that , hopefully you can yield a little better response .
