Ultimately I would like to have enough  rental properties  to replace my full time income.

Ultimately it has 4 units all together. 2 of the units came with tenents. 

In most cases, the lease survives the sale and the new owner must honor it, unless there is a special clause in the lease giving the landlord the right to terminate in the event of a sale. 

I'm currently reading the UBG (ultimate beginners guide) and have encountered a conundrum. 

Since then I've bought 4 more buy & holds, flipped 2 homes, sold 4 of the 5 buy & holds, and have passive investments into various commercial properties including a hotel in Dallas, a new construction of a student housing apartment in Central Texas, a land deal in Austin, TX, and a commercial real estate fund specializing in Class A residential assets in NYC.I'm looking to continue my real estate education, expand my network base, share my knowledge and experiences with others, and ultimately get into syndicating of my own deals.Happy to help anyway I can and look forward to getting to know the BP network!

As far as raising funds, at least for buy and hold, you might want to check out an old article I wrote: https://www.biggerpockets.com/renewsblog/2014/10/21/buy-and-hold-real-estate-is-the-ultimate-investment-heres-why/.

The ultimate goal in determining whether the provider's account fees meet your needs should be the value provided, not just in fees you'll incur, but also including intangible factors such as highly experienced professionals and responsiveness to client needs.Funding Time Frame - I would argue that this is the most important factor, as moving quickly is the nature of the real estate investment community. 

While many will love to leverage as much as possible all you have to do is go back 10 years and those that survived were those who were not over leveraged.

In addition to keyword alerts, you might try working through the Ultimate Beginners Guide if you already haven't done it.

But that is what I would ultimately like to do, it's just to expensive for me right now.
