Doesn't it affect your credit score when every time you want to do business in several MH Parks at a time, your credit is run?  Is there any way around this, especially since I don't intend to live there but only sell...

Here are the key questions to think through before you get it going:1) what do you want to buy2) how much can we afford3) how will you pay for it 3) what are you going to do with it afterHere is how we tackled this challenge:1) Find a reputable and responsive agent to work with: we worked with @Sharon Tzib2) Get pre-qualified with a good and local lender that work with investors: we usedd Rochelle Frazeur from New American. 3) Use some good MLS criteria to set up lists with your agent3) Find out how to identify a good deal: We got our hands on some good cash flow analysis calculators (thanks to @Sharon Tzib) and we used the calculators on BP as well4) Make neighborhood visits to those areas of your interest5) Find other venues to meet up with other investors or go to workshops and meet up's: We've attended BP meet up in Houston, events with Jet Lending, meeting with Wholesalers, and we've met one-on-one with other investors6) Look for non-MLS sources to find properties for sale: wholesalers, and local listing through Rich club or word of the mouth7) Talk to the property manager if you are planning on using on.

Can the transaction qualify for a 1031 exchange?  

Number 1 its a tax right off, number 2 if I send out a house and someone responds I always make them show me via or fax proof of funds that they are a qualified cash buyer before I go wasting their time, mine and the sellers. 

ü The selection and designation of a qualified compliance officer to oversee the compliance effort.

I would avoid properties with exactly 5 units because they can be difficult to resell (most won’t qualify for the financing.)

By that, I mean if I qualify for say a max of $300k for a house, is that the same max for a multi as well?

How do you qualify?

basically I just want peace of mind that I can qualify for a com loan, before I start my search.

Now you're making 4.75K per month and you would qualify for more.
