Some will even give you a credit line up to 90%+ of home value.It would allow you to access a lot of that equity to use for down payments or cash buys.The downside is that HELOCs are usually floating rate.That’s probably the easiest way to minimize fees, keep your properties performing, and expand the portfolio.

However, I have been unable to close because the seller failed to disclose the litigation between them and a 3rd party abutter who sued him when he started to perform sitework.

Or should I go with just getting 2 or 3 secure cards  to start building my credit and ignore taking care of the debt (credit score-610)?

If well estimated, this number can somewhat predict the performance of your investment.However, even if very carefully estimated, NOI cannot predict your share of taxable income (or loss) that will end up on your K-1.

It is precisely after this time when an investment really starts to show you how it is going to perform and a Turnkey company has to earn its' reputation.  

A lot of times, I see landlords advertise that the application fee will be applied either to 1st months rent or security deposit.   

You will want to make sure to get your security deposit note out on time along with a note letting them know they can't use their deposit to cover the last month of rent. 

Lastly do you prefer a full service modern condo buildings with parking, pool, security, gym etc or more an independent SFH with a yard.

The more complex aspects include circumnavigating the security measures intended to prevent scraping from occurring.

Also I am interested in working/helping out with anyone who needs "Boots on the ground" or anything done for multi-family or Single family rentals in the Memphis area since currently I have more time then capital and my goal is to secure my first property (2-4 plex) via an FHA loan by this summer.
